Well for those of us who spend a lot of time staring at our fishtanks, it is likely we have noticed some form of "pack mentality" with our fish. Maybe not all species but I have witnessed it with the Tiger Barbs and now with the Angels and Gourami. The Angels (5 of them) and the Opaline Gourami seem to have formed a pack. They certainly are not always tight together but now with the Dwarf Gourami (the new guy) they seem to wish to check him out as a pack. Nobody is rushing him but they go at him as a large group and he is obviously scared. I am still hopeful that this can work out and am willing to give it a little time as long as I never see anyone hurt him.
Like a Cat or dog, if he swims quickly away, they give chase but don't seem to pursue for real far. When it is feeding time, the dwarf Gourami swims about among them as though there is no issue at all so... I am thinking (correct me if I am wrong) that if he was truly afraid for his life, he would avoid them all the time, even during feeding time? Right before I moved him in I moved a few plants around to sort of change things up and hopefully take away the need for any territorial behavior. Actually watching now, it is only the large Gourami that gives chase but as I said, not far and not seemingly aggressive. More curious and then "oh, you run, I run" kind of thing.
Anyone else have any thought? Should I leave this alone for awhile and just keep an eye on it? Can it get better or no? Honestly, I think if the little guy would just calm down and hold his ground it will all be fine. It is the fact that he runs that the big girl gives chase. Heck she never even hurt any of the Guppy fry so she isn't an aggressive fish typically.
Byron, I think I need you to take a trip over to my house so you can observe this behavior. Ha Ha
If this were dogs, I would have no issue. I can usually spot the tiniest signals a dog gives off but fish??? No clue for sure.
