I have had one Angelicus Botia for about three weeks now. She is pretty much an adult, with much of the black grown in with the polka dot. I just introduced today two young Angelicus Botias. They still look more striped than polka dotted. I found out that I was supposed to keep them in groups and not alone so I purchased the two additional fish. My problem is that the bigger loach is picking on the two young ones. I can't tell if it is biting or pushing but it looks kind of aggressive. It has only been about 8 hours so I probably have to just wait it out for them to get used to each other. Any advice on this? Any mistakes I might have made?
