He’s in a 90 gal. I bought him at a LFS store about 50 miles from my home about 10 years ago. Before I get a bunch of replies telling me the tank is to small I already know. The LFS store advised me he wouldn’t get real big and was about double the width of a number 2 pencil and maybe 12-15 inches long. I loved his coloring and he was different than any other eel we looked at (I still haven’t found one like him anywhere, not even on the web). I think I paid like $49 for him. My tank had a ton of rocks in it and it loved winding through the maze however as he grew I had to remove a lot of the rocks because he got so big he would be rearranging them and they would smack the side of the tank, I was afraid he’d end up breaking it. He has an engineer goby, a blk&whi little damsel that keep him company. He’s scared me a few times by not eating for 6-8 weeks at a time but then he does eat he’s a pig! About 20 sliders every 2-3 days or a ton of squid, clams, and shrimp.
