how many gouramis could go into 36"x12"x16" tank? fake plants hollow logs and small fake rock formations,lots of hiding,and fluval 4+filter for filtration and airation, which i know is for 4' tanks and above but i keep it on lowest setting and figured you can never have too much filtration media! anyway,i dont want dwarfs as they have been agressive in previous tanks ive had. i would also like to know what sorts of gouramis can go together as i didnt want all the same. at the moment ive got 4 corys in there.:grinyes:
