So, I have a 125g with an adult male Managuense, pushing about 16” long. I know in a perfect world I would have my own personal lake for such a fish, but he’s happy in there with the whole tank to himself. Thing is, I bought some rocks for decoration and placed them in the corners, and noticed some incredible hiding places for a smaller fish (that my fish would normally eat if it was in the open). And started wondering if there are any small fish I could get that would be intelligent enough to stay in the rocky area where big hoss can’t get them. Any ideas? Or am I pushing it too far.
