My little dude is a hog. When I put frozen bloodworms in the tanks he will take the hole cube in the corner, wait for it to thaw a bit then swallow all the worms. He is only about 2.5-3" now. Its so many worms that they literally come out of his gills and it looks like a beard of bloodworms. It doesnt seems to bother him, but it sure looks freaky and scares me that he'll choke.
