my kissing gouramis have just recently become aggressive, "kissing" my moonlight gouramis every chance they get, and not because there is food around, no, but because the kissers want the moons out of their way.
sadly, i think i'll have to sell them soon (the kissers)

physics dude, you have a butterfly fish and a BGK in a 29 gal?
