Wow! Thanks all!
Yes, it's a Jag. He jumped out of the tank a few months ago trying to catch a moth or something
Every time I tried to put a cover on the tank he'd knock it off or keep banging into it, so I left it uncovered so he wouldn't hurt himself
The only time he would jump was when being fed, unless there a moth flying over the tank, I thought I got the moth but there must've been another.
