I got a 78 gallon tank, which had fish in when i bought it. I also added the fish out of my old tank, after removing a few and a bit of sorting i now have a 10 inch pleco, 6 albino tiger barbs, 10ish danios, 1 firemouth cichlid, 2 cave tetras, 6 tetras and a red-finned shark. I had two but found a new home for the aggresive one the one i have is quite peaceful. Everybody in the tank seems happy and all have full finage. From my reckoning its only about half stock or there abouts, im thinking of an angel and a gourami, but what else? i dont whant to upset things as i had a bit of trouble when everybody got together but now everything settled, also i live in the uk so some exotic fish may be difficult to get. Any advice welcome, thanks.
