I got him last week. I feed him food sticks for carnivorous fishes. I also tried flakes dried brine shrimps from my betta food. I don’t think he will eat turtle food either because I saw it and it looks exactly like the food sticks I feed him. All he does is hide under the bridge thing. I keep him at room temperature.
I sometimes have a lamp on him when I think it is too cold but it doesn’t make a difference because he hides from it anyway. And I really don’t prefer to buy live food.
