I had 2 a long time ago....They were about 8 inches and one ate my 7.5 inch id shark. I don't know how, but it did. They were mislabeled at the lfs, so that's my excuse for owning them. lol However, I saw 2 in my lfs that were selling as id sharks for $10 the other day. It was hard to do, but I passed on them.
