Thanks for the help guys! I got to weight him today, he weighs 17g. The 24inch is a guesstimate here are a few more pics of him for size reference. The pink's he gets weight 3g each. He got 2 of them today while I was cleaning his tank. I found a chart that said a 16-23g corn needs 2 3g pinkies every 5 days. Is that correct?
