HI Everyone, I made a new setup in my 29 gallon (planted now). The only fish in my tank are cory cats and 1 new baby angel. Over night it seems like half of his tail went missing. A good chunk was taken out and I think it may of been a result of a filter run in, so I turned the filters power down. Will the fishes tail grow back or do I need to pick up something for him? He does not have fin rot and is in great shape, any suggestions?
