hey what's going on guys... i just set up my 20 gallon tank (fully cycled) & put in a neon blue dwarf gourami... a week later i put in a gold gourami & a flame red dwarf gourami... the weird thing is that as soon as i put the 2 gouramis with the neon blue one, the neon blue dwarf started terrorizing the flame red dwarf but not the gold one... so i took the neon blue out... 30 minutes later, the gold gourami started terrorizing the flame red one... it's odd because there was no signs of aggression on the way home, they were even on the same bag! what should i do? ???
