Just set up a new tank, only a small one, and now all water tests r good weve put in 2 ram's, this was yesterday, one of them kept going after the other, and by thismorning the one getting harassed was hideing behinde the filter, so i took the 1 harassing back to the shop to change it. when i introduced the new fish now to the tank the one since yesterday keeps going afret the new 1, do rams live better with more than 2 in the tank? or will they settle?
