I have a 9 inch Polypterus delhezi and i have had him for 2 weeks or so and i have yet to see him eat. I put some freeze dried shrimp in every night and some sinking shrimp pellets in every night before bed. They are gone in the morning but i also have some synodontis cats and a firemouth that may be eating the food. Should i be worried? he comes out after the lights go out and swims around but like i said i havent seen him eat. any help is appritiated. Im new to large fish.
