lol thats good you posted to help everyone lol, i thought it was clear that the 29 was the new tank but i guess everyone reads posts differently, n yeah either get 1pictus or 3, 2 will fight each other, n dont get silver dollars they get too big for your tank and would majorly overstock it, if you really want dithers you could see if some kind of barb or giant danios can survive in there but personally i think the 3 cichlids with the cats will be plenty of activity for the 75 once they are all grown
