Nice cat, always loved these guys. You did get a good deal on it. Cats eat anything, don't worry eventually it will be eating no problem. Nightcrawlers are def a good idea. I would budget for this thing to get big. I've seen a 2 foot specimen. It was sitting at a LFS for LITERALLY over a year and a half, and didn't grow much in that time, so I assume they get nice and solid but I don't get the impression they grow very fast. That said he was of course in a smaller tank than he needed, otherwise looked alright. I myself have also heard 4 feet, but I don't get that impression like I do from the other brachy's like capa, fili, and the rousseuxi (I know I spelt that wrong). I could be wrong, either way have fun with this guy!
