I have a valentini puffer and feed him mysis cubes, shrimp, snow crab legs, among others but im looking for something that will self sustain itself in a 35 gallon tank. I want snails that breed readily with no effort that my puffer can eat. There are certain types that are bad like trochus snails. I will feed the snails too as needed but basically want snails for him to be able to hunt. I put blue leg hermits in there for him to hunt but hes not interested with them, hed rather try to hunt my big zebra turbo which he will never eat hes been trying for over a year the snail does not even care nor does it feel threatened which is amusing to watch but I want to put something in that he can actually eat because that is what he is wanting. He readily accepts whatever I offer him as well. But I have plans to make him start looking for more food rather than wait for me to feed him as much. Hes a good puffer too has not touched any of my GSP’s I also have a ton of it all over my rocks. My puffer’s name is Bloaty and he has a good personality best in the tank.
