I tried her on tilapia last night. She ate quite a pile of the stuff, so it doesn't look like we're going to have any feeding issues.
The babies, on the other hand, wanted nothing to do with tilapia. At least I still have some rainbow trout left for them.

And I still haven't found a good name for the new girl. My daughter is very adamant about finding one we both agree upon, and that has not been easy!
