Aquaria - Living Material
Live specimens are used for a wide variety of studies including studying the physiological effects of drugs on a specimen’s heartbeat and temperature on metabolism, the locomotion of microscopic organisms, and studying plant respiration, photosynthesis, plosmolysis, and more. Algal cultures form colonies of cells that are extremely easy to visualize for better understanding of cell walls and plastids, and many live specimens reproduce rapidly for quick turnover between successive tests.

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".
