Is there any issues with slightly overstocking a Lake Mawai cichild tank? I only ask because I've heard and read in a few places that it is good to slightly overstock cichlid tanks to help with aggression. What are the dangers of overstocking? Is there a way to limit or remove the dangers? eg water changes more often, overfilter the tank, ect. Any info about slightly overstocking would be helpful. I ask here because this is one of the few places I trust for good fish advice. Thank you.
