WClownfish or anemonefish are fishes from the subfamily Amphiprioninae in the family Pomacentridae. Thirty species are recognized: one in the genus Premnas, while the remaining are in the genus Amphiprion. In the wild, they all form symbiotic mutualisms with sea anemones. Depending on species, anemonefish are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches. The largest can reach a length of 17 cm (6.7 in), while the smallest barely achieve 7–8 cm (2.8–3.1 in).
WAnthias are members of the family Serranidae and make up the subfamily Anthiinae. Anthias make up a sizeable portion of the population of pink, orange, and yellow reef fishes seen swarming in most coral reef photography and film. The name Anthiidae is preoccupied by a subfamily of ground beetles in the family Carabidae created by Bonelli in 1813 and this grouping should be called the Anthiadinae. However, both the 5th Edition of Fishes of the World and Fishbase give the Serranid subfamily as "Anthiinae".

They are divided from the subfamily Bythitinae by having the dorsal fin, caudal fin and anal fin all separate whereas they are joined in the Bythitinae. It is divided into the tribes Dinematichthyini and Brosmophycini, with the first having hardened genital claspers and the second soft genital claspers.

WThe danionins are a group of small minnow-type fish belonging to the family Cyprinidae. Members of this group are mostly in the genera Danio, Devario and Rasbora. They are primarily native to the fresh waters of South and Southeast Asia, with fewer species in Africa. Many species are brightly coloured and are available as aquarium fish worldwide. Danio species tend to have horizontal stripes, rows of spots, or vertical bars, and often have long barbels. Devario species tend to have vertical or horizontal bars, and short rudimentary barbels, if barbels are present at all. All danionins are egg scatterers and breed in the rainy season in the wild. They are carnivores living on insects and small crustaceans.

WLeptobarbus is a genus of cyprinid fish that are native to freshwater habitats in Southeast Asia. They are important food fish. It is the only genus in the subfamily Leptobarbinae. Leptobarbus hoevenii or "sultan fish" migrate the fresh water rivers of Malaysia and travel at the surface in schools of 40-80 individuals at speeds of 0.48-1.08 km. Acid-soluble collagen (ASC) and pepsin-soluble collagen (PSC) were extracted from the muscles of selected cultured catfish, red tilapia, black tilapia, pangasius catfish, sultan fish and labyrinth fish, freshwater fishes that are widely consumed in Malaysia. The extracted yields for the tested species were higher for PSC as compared with ASC.

Some species have a modified swim bladder and the anterior vertebrae which enables them to generate sounds. and some of these modifications are sexually dimorphic and make the fish capable of generating sound. They have two rays in each ventral fin and the caudal fin has 9 rays. Most species are benthic and occur on the continental shelf.
