Highly aggressive. Beautiful but socially challenged, male “Siamese fighting fish” will duel with each other — or even with their own reflection in a mirror — and flare their colorful fins in an impressive display of territoriality. When females are present, males will try to “impress” them. Females can coexist; males must be kept separate. Care instructions are included. Size: 1 1/2–2".

Easily compare the different types of structures in a variety of small freshwater crustaceans with this convenient freshwater culture mix.

Predatory. Feeds on Paramecium caudatum. Hay medium.

Characterized by cilia; nearly all possess two types of nuclei.

This large predatory frog will eat any other organism smaller than itself, including smaller bullfrogs; keep similar-sized frogs together to avoid cannibalism.

Two flagella; no chloroplasts. Food organism. Hay medium.

Characterized by flagella; lacks plastids.

Drosophila melanogaster, the common fruit fly, is widely used in genetic studies. They express a number of mutations such as eye, wing, and body mutations. Students can study sex-linked, recessive, and dominant mutations. Drosophila also makes an excellent live food for mantises, small reptiles, and amphibians. Drosophila demonstrates complete metamorphosis with egg, larva, pupa, and adult stages in its life cycle.
