I recently removed my Bass from my main tank, i mixed live blood with dead and it started to work. I think the competition was fierce but now it is different. A tank on their own and it's live only again.
hey i got one of my bass eating pellets (Hirkari gold) by throwing in diced bacon with it, but you will have to a fair few water changes as there forms a nice grease slick on the top lol but it may of helped with the others already eating pellets
