For the last few days it hasn't been eating the market shrimp that I've been throwing in there. It just watches the other fish eat and allows the portion in front of its face to fall to the bottom. Normally its an indiscriminate eater and has been on shrimp for a while now. I've also noticed that it has been increasingly aggressive towards its tankmates to the point where it keeps them cornered to one side of the tank under a piece of driftwood. The moment one of them pokes its head, the LMB chases them back in the corner. Today, I relented and threw a live goldfish and in the tank and it promptly ate it because I didn't want it to starve. It looks like it is regressing back to live only. I want it to continue eating the shrimp. The rest of its tankmates which consits of 2 slightly smaller peacock bass, 1 bluegill, and a decent sized red eared sunfish, are fine except for being scared to death because the LMB lost its mind. Other than not eating the shrimp and its increased aggressiveness, it seems perfectly fine and healthy. I want my mild mannered and only slightly aggressive lmb back.
