So far so good, the new additions aren't as outgoing as the tems but they're also new to the tank but they are taking tilapia filets and that's awesome!
In the past I've fed tilapia filet as well as catfish filet. I keep them frozen. When I'm ready to feed I simply thaw a piece out, cut a chunk off and chop it up into small pieces that won't be too big for the bass. They eat it up too! I kept them pretty fat on it yesterday, they were eating all day!
I like feeding filets because it's A. cheap, B. good nutrition and it's human food quality so it's of high quality C. convenient and D. when they get big you just increase the size of the chunks you feed them!
