Actually took a while to get mine off feeders and bloodworms. She gets frozen krill and cichlid pellets plus crawlers. She stuffs herself!! I feed 6 days a week once per day. The only companions in the 120 are 5 SD and two 6-7" meat eating plecos.Hmm... I got my lent 3 months ago today. He was about 7" then and he's only about 8" now. What do you feed yours? Maybe I'm not feeding him enough? I feed him about 3 pieces of freeze dried krill daily, a nightcrawler 2-3 times a week (no krill on nightcrawler days), and fast one day per week. He's also in a 40 breeder by himself which I know isn't ideal, but I'll be moving him into a 135 when the need arises.
