ok so lately my fei feng (flagtail) is being a little punk and sucking on my retro bichir. it seems like hes scared to try to suck on my arowana or gar. when he is close to my retro once in a while he will suck on his back. i caught him in the act todayy and took him out with my net and held him out of water for about 2 min. and put him back in. i have done this once before, im starting to get worried. should i get rid of him, is he gonna keep acting up? i have 2 other bichirs and he doesnt suck on them only on my retro bichir.
