Hi this is my first post on MFK! So I got myself a couple new bichirs earlier this year, two guinean PBL and a ansorgii, guinean as well. All around the 10" mark. The laps have started to eat pellets during quarantine but the ansorgii did not. For the whole month, I never seen it eat. I tried tilapia, shrimp and sole as well, it will throw itself aggressively on tilapia but only eats 3 or 4 pieces before it darts back behind a rock. It'a still very thin while the laps have put on a couple inches and some girth during that time. No sign of apparent disease. I treated with prazipro during quarantine in case of any potential parasites. Should I move it back in a tank of it's own? What should I do
