I have a betta in a 5.5g tank with an otto and a african dwarf frog. The betta is acting very weird. He has been fine for the last week or so, but in the last two days its has been sitting its elf up ontop of a fake plant that has a leaf that lays on top of the water. So what im trying to say is this fish jumps up on a leaf outside of the wtare and site there with its body half out of the water. so in a way hes commnting suicide! Whats going on here?!?
