Just an FYI, the Aqueon cube and edge lit tanks are not sufficient for Bettas. At least not with the lids that you get with the tank. I KNEW I should have covered the tanks with something else, I even stood back and watched them for a good while before I even let them alone for the night. But the lids are about a quarter inch from the sides I figured since my betta was a king beta the possibility of him getting through the crack wouldn't be too good. But obviously from the title of this post I was wrong. Him and along with the new betta I got yesterday both jumped out of their tanks last night. I should have just went with my gut instinct like we always should because when we don't, we always end up wishing we would have made the opposite decision that we made. I know it's not my water quality because I had it tested yesterday when I went to Petco. He had always been a jumper. He would literally stare at the top of the tank and plot and scheme a way to get out. I have rescued him on the floor before because he decided he wanted to jump during a water change. I go to get more water I come back and he's nowhere in sight. I looked down and he's on the floor. And the crappiest part about it I just put him in that tank yesterday because it was shallower than the tank he was in. I should have just left him where he was. But since he developed swim bladder issues to my knowledge from jumping out of the tank, he would grow constipated and I would have to give him a salt bath every other day for him to use the bathroom. So I figured a shower tank would help him. Because I would find him just hanging out at the top instead of swimming around and I figured it was because he couldn't get to the top very easy. But now I have to suffer the consequences of my **** actions. I should know if nothing is broken I shouldn't try to fix it.
