Hello, I am going to be getting 2 Omnivorous fish Vieja Argentea/Bifaciatus and I was reading that they require veggies in their diet to look their best as well as its good for their health. Now I have no problem giving them veggies its just that I have no idea how i should go about giving it to them. Would I just drop the vegetables in the tank and they will take bites at it or would i chop them up into bite size pieces im lost on this please help. Also what vegetables do you guys recommend feeding. I also Plan on keeping Pothos on the tank with the roots submerged would they feed on this? And is it harmful to the fish? Thanks
