Here's Carnage, my red bellied piranha. This is what he looked like one month ago when I got him from a neglectful previous owner. You can see he looked a little rough.
Thanks everyone. I was pretty pleased with myself when I saw the before and after shots, too. I knew he was looking better, but I guess I forgot how bad he looked in the first place. Of course, it doesn't hurt that I have a piranha guru as my personal adivsor.
That is a pearl danio. Carnage was fed nothing but guppies and feeder goldfish for his entire life before I got him. I've managed to get him eating krill, bloodworms, and live earthworms, but he still eats live fish, as well.
