It's been maybe 2 or 3 month but I thought it could be that she was in a small tank and maybe was causing some internal issues so I now have her in a bigger tank. Haven't really notice her poop being that I have 2 other koi's in there with her but she seems to be eating well. I feed them...
Has any one seen this before, I use to have my koi's In a 55 gal tank and I recently upgraded to a 150 gal tank bc they were getting to big for the tank and now my biggest one which is 12in long is bloated. Does anyone know what can it be?
