I have a pair of Pajama Cardinal Fish and before buying i did some research if it was ok to keep 2. Everywhere i read said it would not be a problem and that they are very peaceful fish. Well i have them in a 20 gallon QT and 1 Pajama won't stop harassing the other. It looks like it just quickly darts at the other cardinal and then lays off. I just don't want the other cardinal to stress out before even going into the DT.
They both still eat like champs tho. Should i be worried?
