Both are about 6" and in the same tank in my 155 bowfront. #1 will stay on the left side and #2 will be on the right. Have seen them on the same side many times with no problems thus far. I know I know... you can't have 2 New Guinea Tigers in the same tank everyone says. I'll just enjoy the moment for now and maybe, just maybe they'll be fine in a larger set up which are in my plans. They are usually a lot more green when stable, but here is a quick clip of both I just took NOW. NO WAITING FOR THEM TO LOOK THEIR BEST! lol... Excuse the debris. Tried the wardley shrimp pellets for the first time and that stuff just breaks apart and clouds like a mofo.
