A very peaceful species, that does not make an ideal community fish due to its small adult size. It is easily intimidated by larger tank mates and will not compete well with them for food. [13] 42.4 L (11 gal) [13] 72 to 79 °F (22 to 26 °C) [13] 6.4 to 7.4 [13] Rust corydoras: Corydoras rabauti: 5 cm (2 in) Mosaic corydoras, reticulated corydoras
Tropical freshwater aquarium. Freshwater fish may be either coldwater or tropical species. Although freshwater aquariums can be set up as community tanks, coldwater and tropical fish are generally not mixed due to incompatibilities in temperature requirements. Coldwater aquariums house goldfish and other species that do not require a heating ...
The examples below are for small freshwater fish; larger freshwater fishes and most marine fishes need much more generous allowances. 3 cm of adult fish length per 4 litres of water (i.e., a 6 cm-long fish would need about 8 litres of water). [74] 1 cm of adult fish length per 30 square centimetres of surface area. [75]
With more individuals in the tank, kuhli loaches tend to be more active and less shy. kuhli loach groups of this size can be kept in 20-gallon aquariums but can be housed in something larger if given enough hiding places. Other species that make good tank mates include tetras, minnows, shrimp, corydora, danio, and other non-aggressive fish.
These fish are best kept with live or frozen feed and they easily outgrow the tank within eight to ten months. An aquarium with the minimum diameter of 6 by 3.5 feet (1.8 by 1.1 m) and 300 US gallons (1,100 L; 250 imp gal) is suggested as a bare minimum but 400–800 US gallons (1,500–3,000 L; 330–670 imp gal) is the best way to go.

The scales are small but well visible, and some may be black and form isolated dark spots on the lower sides. The dorsal, pelvic and anal fins each have 8 rays. The pectoral fins are broad and have 13–18, but more usually 15–16, rays. The fish has no teeth, adipose fin, or spines. The mouth is relatively small and the tail is forked.
Breeding adults have numerous large pointed tubercles on the top of their heads, smaller tubercles on their pectoral fins and a red or orange spot on the upper opercle behind their eyes. Juveniles look similar to adults, but have more obvious lateral stripes and caudal spots, and their tails are typically more reddish than the adult's tail.
The smallmouth bass (Micropterus dolomieu) is a species of freshwater fish in the sunfish family (Centrarchidae) of the order Centrarchiformes. [4] It is the type species of its genus Micropterus (black basses), and is a popular game fish sought by anglers throughout the temperate zones of North America, and has been spread by stocking —as well as illegal introductions—to many cool-water ...
