He is my first senegal bichir I bought him I think 3 months ago and he is 5" and now he's only 6" am i doing something wrong? He's in a 50 gal with my 6" bgk, 3" blood parrot and 3" gold sev (a 125 is waiting for them though I can't put them there yet cuz my JD will bully them waiting for them to grow ), also I change 50% of the water every week 25% per 3-4 days. His diet is O.S.I Shrimp pellets, Hikari sinking carnivore, sometimes getting a bite of cichlid gold for my cichlids, also market shrimp for his treat. Ammonia - 0 Nitrite - 0 Nitrate - 14. I always make sure that the ammonia and nitrite levels is always 0. Is this normal? Can anyone help me if I'm doing something wrong.
