I got two of these little guys at like an inch and raised them up to be about 4". However, I recently turned my set-up into an african river bio-type and had these guys sitting in my 30gal grow-out tank until I figured out what to do with em. Sadly one of my baby bichirs decided that they looked tasty and snagged one up so I have decided that I need to get rid of this other little guy. I was super excited to raise these little guys out, but for the safety of this last guy I need to re-home him. He is still on feeders and I have had little luck converting him to prepared foods but that is common of these little guys. Will post a picture when I get home!
