I know feeding is always discussed but I'm new to piranha and want to make sure they are perfect. I picked up a package of frozen bloodworms to start and just feed them a cube today and they seemed to love it. Is it also ok to keep feeding them a cube a day? Or should I feed them 2x a day? Also, is there any harm with just keeping them on a bloodworm diet or should I get some other stuff and what? Let me know!
