All was seeming well in the tank since my last message, but unfortunately, I'm beginning to worry again. The bully fish is at it again, and this time worse than before. I'm not sure if I should just try the separation method again or if there is something more I should do. I've heard about putting a divider in the tank but I don't want to restrict their room and cause them too much stress. I'm kind of at my wits end with this guy. It is only the weakest fish that he is going after now, and I've been watching closely and noticed him bumping up again that fish and it looks like he's taking a bite out of him, too. I definitely don't think that's normal... at least, I hope it isn't! The weaker fish has completely lost his beautiful tail fin and has only a little stump that wiggles around when he swims. Its always the fins that the bully fish goes after. I've tried doing some googling to see if I could find a solution, but the only consistent response I could find was that a fight for dominance can happen if the aquarium is too small. I've done a ton of research and everything I've found points to a 60 gallon tank being big enough for 3 normal goldfish.
If you've got any info that might help out, Thor, I'd really appreciate it.
