oh thanks so much Vincenia i always confuse kuhli loaches with dojo loaches.THEY grow to 6 inches the kuhlis grow to a more appropriate size.also most of the time dwarf gouramis will eat shrimp,snails are good tank mates with just about any fish as long as you add a form or calcium such as cuttle bone.dwarf frogs,they are kinda hard to feed since they have bad eye sight.they can mistake your betta's tail for food or eat your shrimp or even eat your cardinals,on that last one maybe.
