Ok thanks for all the advice. One last question if i were to put gouramis and rasboras would their be room to put two species of corydoras in groups of 6 or would i be ovrr my stocking level
That would be OK. Depending upon how many Pearl Gourami, you could have two or three shoaling species in numbers of roughly 7-9 or more, depending upon species. And the group of cories.
