9 weeks ago I purchased 2 red spotted severum (super red). They were about 3". I put them in my 75 gallon with a couple blood parrots. One of the severum continually hides in the corner and I thought he was being bullied so after about 10 days of this I put him in his own 10 gallon by himself. He still hides constantly. He will not even eat if I am in the room. If I take his hiding cave out he shoves himself behind the filter. Not sure what to do. He looks very healthy and is growing fast. I just don't want a fish I will never see. The other one is doing fine in the Comunity tank.
