So today I introduced 2 1 month old clowns into my 30gal tank that finished cycling two days ago. My readings before adding the fish were 79 degrees Fahrenheit, a ph of 8, ammonia 0, nitrites 0, nitrates 20ppm. I acclimated them properly but even in the bag this clown was acting kinda strange. It is swimming near the bottom and trying to hide, the other is acting perfectly normal but is nipping and ramming it. Is this simply a dominance battle?
