Are polypterus night eaters? And did you mean put the tilapia where the aro can’t eat it? Or can eat? It really seems like he just swims pst the food at the bottom of the tank. Even picks it up and drops it like he’s not hungry or something.
Hikari Carnivore vs massivore?? I’m going to try to get the aro on Hikari food sticks. I’m assuming it doesn’t matter which type exactly but I would rather have him on food sticks. Then some thaw food and occasionally live feeders.
Im sorry i meant where the aro CANT get it. Bichirs are nocturnal but will learn to feed with the lights for now since its adjusting try feeding it after lights out.
Id go with carnivore since they are smaller. At 1st i would offer tilapia though. It will eventually settle in amd eat.
