The lemon tetra (Hyphessobrycon pulchripinnis) is a small fish originally found in the Amazon River. These fish are commercially bred in several countries, so wild specimens are very rare. The lemon tetra grows to an adult size of 1.6 inches long. Adult males tend to be less deep bodied, slightly smaller, and more intensely colored than females.
The lemon tetra should be maintained in an aquarium of 20 gallons or larger. A soft, sandy substrate (CS6631) is a good choice. Driftwood (ZM2000) and live or artificial plants may also be incorporated.
The lemon tetra is an adaptable fish that prefers a temperature of 68°F to 82°F, a pH of 5.0 to 7.5, and a hardness of of up to 2 to 20°H.
The lemon tetra is an excellent fish for a community aquarium as it is lively and peaceful. Keep it in groups of 8 or more for the best effect. Good tank mates include small peaceful barbs, livebearers, danios, rasboras, dwarf gouramis, cory catfish, smaller Loricariids, other tetras, pencil fish, and peaceful dwarf cichlids.
In the wild, the lemon tetra is most likely omnivorous feeding on small invertebrates, crustaceans, filamentous algae, and fallen fruit. In the aquarium it will accept dry and frozen foods of similar sizes. Good choices include frozen bloodworms (SF4792) and cyclops, as well as high quality flakes that include some vegetation (AL165). For maximum color, growth, and health these fish will look their best when given probiotics (AL169) in addition to a balanced diet.
