The Yellow Clown goby is an attractive and peaceful little fish. It has a stubby body and a large head. It is nose-to-tail bright daffodil yellow all over. Males and females are visually identical. It grows up to 1 inche; we recommend an aquarium at least 5 gallons, or at least 10 gallons for a pair.Clown gobies are entertaining little fish who spend most of their day out in the open where they may be enjoyed. They typically perch on top of rocks or coral, or even use their fins to stick to the aquarium's glass. This suction cup-like fin allows them to be comfortable even in very high-flow environments.In the wild they make their home in the branches of SPS corals, mostly Acropora, however it is not necessary to duplicate this in the aquarium. If a pair is kept with these branching corals they may use the coral as their nest, clearing away a small area of its polyps so they may lay their adhesive eggs on the coral. This does not harm large established colonies, but may be too stressful for small or weak corals. In the aquarium a clown goby may host with any number of corals that it would not associate with in the wild, making a very interesting display. They do not hurt the coral but rather enjoy spending time within its tentacles.Most clown gobies are scaleless, and their smooth skin is covered in a noxious mucus that gives them a foul taste. Most predators would spit them out, however caution should still be used when combining the clown goby with large-mouthed fish, as greedy predators may still swallow them.Clown gobies are not prone to jumping from open top aquaria. They may be territorial towards other clown gobies, so we recommend they all be added together to a sufficiently large aquarium at the same time. They are typically peaceful with all other types of fish.Clown gobies are primarily carnivores and their diet should include plenty of high quality meaty items, marine algae, Spirulina, and frozen Mysis shrimp. It is preferable to feed at least twice a day. Frozen food is best, however in time they may learn to eat dry foods.As one of the largest families of fish there are near countless varieties of gobies which inhabit every different niche on the reef. They are coral safe and typically quite active and friendly with other fish. They have the ability to change sex to form pairs, although they don't always do so. Most gobies are imported from the Philippines.Gobies are diminutive fish typically with elongated bodies, and as such we do not recommend any aggressive or large-mouthed fish to be kept with them; this includes all groupers, snappers, sweetlips, soapfish, lionfish, eels, goatfish, anglers/frogfish, leaf fish, etc.
Wrasses are prone to jumping from the aquarium when startled or excited so we recommend a secure lid. They feel most secure when there is plenty of live rock to hide in, as well as open space for swimming. Most species may be kept in pairs or harems as long as they are added together or females first. They do not appreciate living with other species of wrasse, so any aquarium with several species must be large enough and the most peaceful species added first.They should be fed two to three times a day plenty of high quality meaty items, frozen Mysis shrimp, krill, chopped seafood, marine algae and Spirulina.Coris wrasses are easy to keep and have active personalities. They have big appetites for invertebrates, especially shrimp; however larger species may attack other crustaceans, snails, worms and starfish among others. They are often employed to eat pests of corals and clams including flatworms, fireworms, Montipora eating nudibranches, and pyramid snails; they may occasionally clean their fish tank mates. They do not bother corals or anemones, but may flip over rocks in their search for food. Large species may also bully or eat small fish, but they are typically nonaggressive with other large fish as long as they have a different shape. Similarly shaped fish are seen as a threat and may be targeted; we do not recommend keeping them with small species such as flasher wrasses.At night time or when threatened Coris wrasses will dive into the sand for protection. They can even swim under the sand to avoid predators. It is not uncommon to find the wrasse laying on top of the sand to rest during the day. A fine sand bed of at least 2-3 inches will help them feel secure. Rocks should be placed on the aquarium glass and sand poured around them to eliminate the danger of a cave-in when the wrasse dives in. The Yellow Coris is a breathtaking fish colored bright lemon yellow all over. As a juvenile it has three black eyespots on its dorsal fin and one at the base of its tail. When mature it has only one black spot at the front of its dorsal fin, and develops handsome highlights of orange and turquoise on its face and fins. It is very similar to the Four Spot Coris wrasse, however the Yellow coris has a solid yellow belly. Other names include the Canary or Golden wrasse. It grows to 5 inches and needs an aquarium of at least 70 gallons.
Echinoderms such as cucumbers are extremely sensitive to changes in the water quality. They require well established aquariums for both water stability and sufficient food supply.This delightful animal is a bright sunny yellow sometimes with greenish stripes. It uses its tiny tube feet to attach itself to its environment in an area of high water flow, extending its feeding tentacles to catch tiny floating food particles from the water. If provided with enough food it may reproduce by division. It grows up to 2 inches long.Covers over all intakes are required or the cucumber may accidently become sucked inside. Like other filter-feeding cucumbers its body contains holothurin toxin. This species is unlikely to cause problems, however, because it contains only a very small amount of mild toxin. A water change and fresh carbon should be used if it is noticed a cucumber has died. Echinoderms such as cucumbers are extremely sensitive to changes in the water quality. They require well established aquariums and addition of supplemental foods such as phytoplankton. If it is starving it may shrink in size or lose its feeding tentacles, at which point food supply should be increased.
Jawfish are some of the most personable fish available. Their huge eyes miss nothing in the aquarium, and peer through the glass at their keeper. They may then cock their head to the side like a puppy as they interact with their owner. Aggressive tank mates and fish with large mouths should be strictly avoided, as should any animal that may disturb the tranquility of the sand bed: sleeper gobies, pistol shrimp, burrowing wrasses, goatfish, etc may stress the timid jawfish out of its burrow. Unless the aquarium is large jawfish may also stress each other. They use open mouth threats, and when that does not work they grab mouthfuls of sand and dump it in the other fish's burrow. Suitable tank mates include non sand-dwelling gobies, peaceful blennies, cardinal fish, clownfish, flasher wrasses, chromis, dragonets, assessors, etc. They may consume tiny fish such as Trimma or Evotia gobies, and shrimp such as sexy shrimp. Because of its extremely shy demeanor, we recommend the jawfish be the first fish added to the aquarium.Jawfish are sand dwelling animals and use their large mouths to scoop out a burrow to live in. At nighttime or when a tunnel is not being used the fish may block it off with shells and small rocks. It is important to provide deep sand of at least four inches, preferably deeper, with plenty of shells and crushed coral of various sizes so the fish has enough building material to create a stable dwelling. The shed leaves of Halimeda algae are also utilized as building material. Rocks should be placed on the aquarium glass and sand poured around them to eliminate the danger of a cave-in when the fish excavates. Plenty of open swimming space may encourage the jawfish to hover higher above its burrow. We recommend the tank be securely covered as jawfish are prone to jumping from open top aquaria.Jawfish are primarily carnivores and their diet should include plenty of high quality meaty items, marine algae, Spirulina, and frozen Mysis shrimp. It is preferable to feed two to three times a day and to let some food land on the bottom of the aquarium. Frozen food is best, however in time they may learn to eat dry foods.The Yellow Head jawfish is a spectacular fish with a ghostly blue body that shimmers in the light. Its head is an intense lemon yellow hue. It is commonly available from the Caribbean. Males and females are identical. It grows to 4 inches and should be kept in an established aquarium of at least 30 gallons.
The Yellow Head sleeper goby has a lovely greyish white body the color of dolomite. Its face is emblazoned with an electric blue stripe on the cheek and bright lemon yellow on the mouth and eyes. Males and females are visually identical. It grows up to 6 inches; we recommend an aquarium 50 gallons or larger.Sand sifting, or sleeper gobies, are famous for their busy work of keeping the sand looking clean and free of debris. They require a fine sand bed of at least two inches in order to feel secure and also to exhibit normal behavior, which includes near constant sifting of the sand through their gills. They do this to extract any edible particles, such as small shrimp and copepods, worms, algae and more. They are so efficient at eating micro-fauna from the sand that unless the aquarium is large we do not recommend keeping them with live-food dependent species such as dragonets or signal gobies.Sand sifting gobies have large mouths and may eat very small fish or shrimp, but are peaceful with all other types of fish. They may fight with other sifter gobies unless each fish is given at least 50 gallons worth of space. We recommend the tank be securely covered as sand dwelling gobies may be prone to jumping from open top aquaria. Their bottom sifting activities also leave them vulnerable to intestinal parasites and we recommend de-worming them before adding to a display aquaria.Sleeper gobies are commonly mistaken as watchman gobies; however sifter gobies are lone fish that do not pair with a pistol shrimp. If two fish are added to a sufficiently large aquarium at the same time it may be possible to keep a pair of sleeper gobies.Sleeper gobies are primarily carnivores and their diet should include plenty of high quality meaty items, marine algae, Spirulina, and frozen Mysis shrimp. It is preferable to feed more than once a day. Frozen food is best, however in time they may learn to eat dry foods.As one of the largest families of fish there are near countless varieties of gobies which inhabit every different niche on the reef. They are coral safe and typically quite active and friendly with other fish. They have the ability to change sex to form pairs, although they don't always do so.

Better known as the Melanurus wrasse, and sometimes as the Hoven's wrasse, this popular fish supplies bright colors and plenty of activity. Females and juveniles have deep yellow and aqua colored stripes along their bodies and fins, and a dark eyespot in the middle of their dorsal fin and at the base of the tail. In males the stripes become magenta and electric blue. Males also lose the eye spots, but develop a dark edge to the caudal fin which becomes a spot when the tail is compressed. A yellow patches develop behind his eye and at the base of his pectoral fin, and five lighter aqua colored saddles can often be seen along their backs. It grows to 5 inches and needs an aquarium of at least 70 gallons.
The Yellow Watchman goby is an iconic fish that is an incredibly bright lemony yellow all over. Depending on its mood this color may darken, and several wide bands may appear along its body. Its back and fins are speckled with sparkling sapphire spots. It may be especially territorial towards similar species. Males and females are visually identical. It grows to 3 inches; we recommend an aquarium of at least 10 gallons. It prefers to pair with a Tiger pistol shrimp.Shrimp gobies go by many names including prawn gobies and watchman gobies. They may be kept on their own just fine in an aquarium; however it is especially fascinating to pair them with a pistol shrimp. The goby will form a strong bond with the shrimp and mutually benefit each other. The hard-working shrimp will excavate a burrow under the sand for them to live in, consisting of several tunnels, entrances and exits. The sharp-eyed goby stands guard at one of the entrances and keeps an eye out for threats. As the shrimp goes about maintaining the tunnel and searching for food it keeps one antennae on the goby. If the goby sees danger it flicks its tail, signaling to the shrimp to make a hasty retreat. The goby may follow quickly if the danger is threatening enough. At nighttime or when a tunnel is not being used the shrimp will block it off with shells and small rocks. It is important to provide deep sand of at least three inches and plenty of shells and crushed coral of various sizes so the shrimp has enough building material to create a stable dwelling. Rocks should be placed on the aquarium glass and sand poured around them to eliminate the danger of a cave-in when the shrimp excavates.We recommend a shrimp and its goby partner be added to the aquarium at the same time; it is best if they are placed in a net together and gently lowered to the aquarium bottom. There are three common types of pistol shrimp that pair with gobies; the Tiger, Fine Striped, and Candy Cane pistol shrimp.Unless they are a pair shrimp gobies tend to be quite territorial with each other- if more than one is to be kept in the same aquarium we recommend space enough to accommodate at least 24 inches between burrows. They are typically peaceful with all other types of fish.We recommend the tank be securely covered as sand dwelling gobies may be prone to jumping from open top aquaria.Sand gobies are primarily carnivores and their diet should include plenty of high quality meaty items, marine algae, Spirulina, and frozen Mysis shrimp. It is preferable to feed more than once a day and to let some food land on the bottom of the aquarium.

Zebra Danio Brachydanio rerio Rasboras, Danios and Barbs are a highly sought after fish in the hobby. Not only do they beautifully school in the upper areas of your tank, but they also remain rather small, so they are a perfect addition to many smaller sized aquariums. They are a peaceful fish that enjoy the company of others of its species, a school of at least 6 is recommended to keep them feeling safe and secure, but adding more is a welcomed idea.Rasboras, Danios and Barbs generally grow to a size of around 2 inches, so a tank of at least 10 gallons would be best suited for the Rasbora fish, as they enjoy having enough space to swim around in their school. Planted aquariums would provide them with ample spots to hide in and weave through as they are swimming about. Rasboras are omnivores and should be fed a well-balanced diet of freeze-dried bloodworms and quality flake food. Zebra Danio Specifics Zebra Danios grow to a size of 2", so a tank of at least 10g would be best especially if kept in a school of 5 or more. Their temperature should be set between 64-74oF and their pH between 6.5-7.0.
