i already have just two tinfoils in my 4 foot aquarium. i have two featherfin cats, two mollies, two silver sharks, tiger barbs and a plec. if i try to add more tinfoils to increase the size of their shoal, will the two i have attack them? also the two already there spend most of their time bumping off each other, whats that all about?
my tank is 4ft by 1 by 2ft. i do the partial change every other week, the filters (2 fluval 4s) are mature, there is nothing dead as far as i know, but it keeps going green and smelling. the nitrate and nitrite levels are within the boundaries and i have algae eaters in the tank. it smells like a dirty nappy. help my husband is threatening to eat my fish.
