I just visited a lfs that I have never been to before. They are very knowledgable and I will probably go there again. At another fish store I saw the same kind of rainbow fish selling for 20.00 and at this store they were selling for 4.00. They also had discuses there for 20.00. This was really cheap, I thought. There wasn't any thing wrong with the fish that I could tell. Good store in my eyes. Are rainbow fish usually that cheap and should I go back there and buy the whole tank full?
