I've been wanting a african dwarf frog in my tank... but I've heard they're not good to put with tiger barbs. So what else can I put ? Shrimps? Snails? Crab?
hmmm. something fairly aggressive that can hold it's own but your kinda limited with your tank size and the amount of fish already. Tiger barbs get 2.5-3" so I would just not add anything honestly.
