I have seen the gourami mess with all the bichirs. but usually just when they are swimming in the water column. that lap is one of the least active ones in the tank and i have never seen the gourami mess with that one at all. would another bichir do that? ive basically had the same fish in the same tank for the last couple of years. ive traded or sold some of the bichirs but the ghost knife and gourami have been there since the beginning. i have read about ghost knifes eating the eyes of other fish, but i didnt think that would include beady little bichir eyes.
