really cause in tanks poly sens get about a ft long an i think 16" in the wild.
Bichirs require a lot of floor space; the height of the tank doesn't matter. You should note that since these specimens can grow over 12" long, they should be kept in a 50+ gallon tank. There should be a gap of air in the tank allowing the bichir to gulp air, the tank can't be full of water. Bichirs are escape artists. Without a secure lid on an aquarium, the fish will eventually escape, and go quite a long distance before drying out and dying.
