People don't realize how active they (bettas) actually are, they seem to have it in their heads that if you give a betta a large tank he'll "just sit in a corner and make a bubble nest" which is soooo far from the truth it may as well go in the same category of ignorance with "fish only grow to the size of their tanks" because it really is a stupid way to think.I am trying to get a bigger tank for mine. Had to rescue a khulo loach from my brother that he rescues since it wasnt getting food
Bettas are extremely active when in a "large" tank, they'll explore every crack and crevice and are always doing something. Great fun to watch.
