what type of bichirs are doing it for you? its 99% the endlis doing it in my tank. I had a del that would join the fun sometimes and every once in a while an ornate will jump in. I have two laps in the tank now but i have yet to see them do it. The laps are also the smallest fish in the tank so they may just not feel confident to get away from cover.
is it a bad sign when they jump? i mean like is it tht the tank too small or they dont like the tank?
