And you will not be disappointed! My fire eel, Apollo, has so much personality it is amazing. I put in a P. ansorgii and they are best friends. Seriously, they even hunt together and swim around together when I put in live blackworms. Neither of them have scratches or any kind of marks so I know they don't fight when I am not home. (Thank god).
For reference where I live its hard to find a place that has em (very few LFS left within a reasonable distance). I got mine for $19 at 5-6 inches. He was the only one left and they only get about 10 a month. But, holy crap do they grow fast. He is averaging about 1-1.5 inches a month right now. He is kissing 12 inches currently.
He also comes out every time I walk near the tank and will even follow my finger along the glass. I feed him by hand so water changes can get annoying since he will always attack my hand for food. Recently he even comes out and "dances" when I get ready to feed him.
Hope you get him and you will enjoy him very much!
