Thank's for the tip. By the way my temensis's are doing great. They're eating like crazy and looking much more natural in their home. I put a bunch of feeder minnows in the tank so they can hunt when they want.
So here are the updates. 4 Days later. The minnows are almost gone. Man can these guys eat. I can't figure out how they can digest the minnows so fast. Here's another photo that I took of my Guapotes just for the hell of it. It turned out pretty cool.
