Hi, I have recently upgraded to a new tank ( and i love it! corner aquarium, i actually have no need for a tv anymore!!! ) Anyway today i bought a new angel fish! I already had one in the aquarium. Now the new fish is gettin bullied badly, evertime it tries to come out into the open the old angel fish chases him. The new fish looks stressed! Any tips? What can i do??? The fish are of similar size! Help!!!
