I have a lonely fish that came from a pond. I believe it is a some type of minnow, but I don't know anything about pond fish. I'll post a picture.
For now it is sitting in a little container of water. Does it need a filter and air circulation? Could I temporarily place it in a tank with just a few tetras until I can do something with it? Should I find some more fish like it so it may school? (If so, would I need the same type of minnow, since I don't know what kind it is?)
Should I maybe just find a pond and release it back into the wild?
I can get my hands on other minnows from around here easily enough if I need to. But I'll release him if I must, too.
