which do u think is bad for the tank? all the fish are pretty good right now...not attacking anyone, its heavily planted and many many places to hide...all the fish are no more then 2.5 to 3 inches the shark i had to take out cause he had fungal infection so im nurseing him back to health...but all in all it was justed the stressed out from the new arrivals but everyone is minding there own business now...i know there are people out there that know more then me about cichlids and stuff, and this is not to disrespect them but when u say a bad combination of fish togeather, dont u think the fish will learn to addapt to its surroundings, not only the water but the tank mates...not just oh this ones bad to be with this one...u dont think they will get used to eachother eventually. hope i didnt offend anyone.
