Aquarium parameters are all good, ammonia zero. 2 weeks ago got 6 little barbs, 3 days ago got 3 platys and 1 pleco. We got him 3 days ago. Just want to know how is this guy normal behaivor. He has been active just the first evening and after that he has been hiding himself all the time. We wanted to feed him last night and after light went off and other fishes seemed to calm we let algae wafer down... hahaaa all barbs got so active after that and started looking until find and had a good and long dinner, so I don't think pleco got any. We are a little worried for that hiding as well or is it normal???
