Hey peoples, my tank is nearly fully stocked and looking at it the top 1/3rd of the tank is empty apart from 3 Pearl gouramis. The tank is a 240L Rio and im looking for ideas for another topdweller or school of top dwellers, i currently have the fish listed in my stocking and once ive added the final 7 fish i will be up to over 90" of fish (fully grown calculations obviously) so is another school of fish advisable?
