alright i just bought a JD chchlid and a African chchlid today from petco(they are both babies about 2-3in long as of now),my tank has been cycled and it is a 30gal tank(yes iam aware the JD becomes much larger) and next week iam getting a 55Gal tank from a friend of mine to put them both in there or just the JD?(Btw i also have a gold fish who is healthy as all can be in the tank with the 2 chchlids)now my question is this...the african chchlid occasionally goes after the JD like chasing him and at times nipping at him and the JD does nothing back such as chasing of nipping at him he just swims away from the african chchlid BUT neither of the chchlids do anything to the gold fish,is this normal? why is the african doing this? should i return the african? i dont know what to do? help!
