A few months ago I had to get rid of a 75 gallon tank before I really wanted to because we had a baby on the way and I would be losing my fish room to the baby unfortunately and my wife wanted the room dont like 8 months before the baby was born. I decided to put the fish from that tank into my 300 gallon for the time being till I could get rid of them. The fish consisted of a few peacock bass which I wanted to keep and some smaller fish like 2 geophagus and a catfish that was growing too slow. In the 300 gallon is a mbu puffer. I woke up to this tragedy this morning after months of cohabitation.
