So, i have this loach. MY bofriend saw it at the fish store and thought it looked cool so we took her home. We dont exactly know what kind of loach it is but after looking it up he says its a botia kubotai. well anyways the problem is that its swiming around in circles, not like giant circles really fast at the back of the tank but more like chasing its tail all around the tank sometimes fast enough to jump out of the water abit. then it rests on the bottom of the tank on its side breathing heavily. he spends mos of his time on the bottom of the tank in various tank ornaments hiding out but randomly will swim like this. ive only seen it do that twice. i cant tell you the water specs because i dont have an at home test kit but its a 20 gallon tank with 4 female bettas and a school of endlers(2 mails 3 females). anyone have any idea?
