Thanks for your resonse, My fiance and I are planning to get a much larger tank within the next two months, most likely 65-100g.
My current situation is that I have two loaches, one is 3 inches long, the other is 2 inches long. The larger loach seems to bully the smaller one sometimes, yet they are also together most of the time. I've got another loach (approx 1.5 inches) in another tank with three cories, he seems to be doing well however I am wondering if it would be better to place all of the loaches together. My fear is that the larger ones will be aggressive toward the smaller one.
