Betta housing system. A) Standalone recirculating housing system, with automated dosing system and rows supporting multiple individual tanks. B) Top: 2.8-L tanks housing multiple late larval fish; bottom: 1.4-L tanks housing single adult fish. White acrylic dividers are placed between tanks holding adult fish to prevent aggressive display. Individual tubing provides constant water flow to each tank, displacing water from the back of the tank where it begins the water filtration process. C) Side view of 1.4-L tank containing a single adult fish and suction cup plant enrichment item. Lids and baffles at the back of the tank prevent fish from escaping into the system.
