Here's my little boy when I first got him, November 2012.
And here he is now.
He's a bit chubbier, but very active. In a 5 gallon spec, with a pile of rocks, a few small branches, micro swords, java moss, salvinia. A few snails, which he bullies. A lot.
Thanks! I like him. He's a grumpy little bugger, active, and seems healthy. I'm pondering putting a giant amano in with him to help deal with some of the algae that's on a few plants. Shrimp would be as big as him, so hopefully he'd ignore it.
