my danios (3) seem to harrass my dwarf gourami, (male) they've shredded his fins a bit, so having a back up plan wouldn't hurt!
all the best.
My zebras aren't bothered by the gouramis in my tank, I have probably 10 or more zebras in the tank, and 2 gouramis.
what about guppies,platies,mollies and swordtails? would they get along with a dwarf gourami
