I pumped my whole comm for close to a month on quarantined live feeders... Then all of a sudden stopped the feeding. 3days later threw in MP, 1 ate. Next day throw in some more, more take. By end of the week, all are on MP. So far it's worked for me... The only one I haven't had any success with so far is the L14... 2 months already and I still haven't seen it eat anything... Somehow, he still seems to have a lot of energy, coz when I try to shift him to observe the stomach, he fights back... Really fights back.
