I have my Betta, Howl, in a ten gallon and used to have 5 neon tetra and 4 cherry shrimp in there as well. Slowly the population started dwindling but I was perplexed because I could never find any dead fish and the shrimp seemed to just disappear. As of today, Howl has eaten everyone! Has anyone else had this happen?
I feel like I'm going to have to get him his own smaller tank and get a new Betta for the ten gallon, and hope that the new Betta doesn't feel the need to eat everything too!
