So currently in my 220 I have 5 tiger silver dollars, 4 bala sharks, 3 tinfoil barbs and a flagtail. Would this be over stocked, or full? Don't want to add anything else was just asking others opinions. Filtration is an ehiem 2262, Fx-5 and three Aquaclear 110 and I do two water changes a week. Just looking for some input from others.
