I have an African Pike hepsetus odeo, he is about 5 inches and loves goldfish. To bad i don't, im worried about parasites and diseases. Im bad at starving fish especially when its an 80 dollar fish, well i paid 50 because i work at the store he came from. I just really want him on anything but goldfish, i dont care if its tilapia or pellets. Im just so worried any suggestions would be great thanks.
