The terms shell dwellers or shelldwellers, shell-breeding, or ostracophil are descriptive terms for cichlid fish that use the empty shells of aquatic snails as sites for breeding and shelter. The terms have no taxonomic basis, although most shell-dwelling cichlids are from Lake Tanganyikas lamprologine lineage. [ 1 ]
In the wild, the bumblebee cichlid is a specialized eater, but in aquarium they can eat whatever that is fed to them. Like other mbuna cichilds, this is a hardy and very aggressive fish that should be kept in a species or mbuna tank. The best practice is to keep one male with several females. Breeding is relatively easy.
Among cichlids, paternal mouthbrooding is relatively rare, but is found among some of the tilapiines, most notably the black-chin tilapia Sarotherodon melanotheron. In the case of the maternal mouthbrooders, the female takes the eggs. Maternal mouthbrooders are found among both African and South American cichlids.
Dither fish are typically fish that swim around the top of a tank, a behavior that reassures more timid fish that no predators are nearby, and are found naturally in the same habitat as the other fish in the aquarium, thereby encouraging them to relax and engage in normal behavior.
Convict cichlids are serially monogamous, so pair bonds may form first before they establish a territory together, or the male and female may each obtain a territory before pairing with each other. [39] Because the convict cichlids are also substrate-brooding, this territory will include a breeding site for the deposition of eggs. [40]
Many color and tail pattern varieties exist. They generally need a ratio of 1 male to 2 females or more. All guppies and mollies are hardy fish that tolerate lower oxygen levels and temperatures than most aquarium fish, give birth to live young, and readily breed in home tanks. [58] can live in full sea water [59] 66 °F - 84 °F (19 °C - 29 °C)
Breeding: 30 gallon minimum for 1 male and 5 females; community: 55 gallons; species only: 1-4 in a 10 gallon; 5-7 in a 20-gallon, 8-10 in a 30-gallon, and 11-15 in a 45. These fish prefer open swimming areas as well as many caves. The aquarium would optimally include a sandy bottom, robust plants, caves, and rocks.
Tanks in a shrimp hatchery. A fish hatchery is a place for artificial breeding, hatching , and rearing through the early life stages of animals—finfish and shellfish in particular. [ 1 ] Hatcheries produce larval and juvenile fish , shellfish , and crustaceans , primarily to support the aquaculture industry where they are transferred to on ...
