Nail it Lizzard!! Can you get any pictures of it? Would hate for you to pay $40 for a 5" sp.'bellycrawler'. Really, thats still a little high for a Saxatilis of that size, normally they should be in the $15 to $25 range. All depends on availability though.
Pikes aren't for everyone though...

. Some people just can't handle them, which really doesn't make much sense to me. They are no worse than most aggressive CA cichlids, and people are still keeping them. Anyway, they can be aggressive, but generally are pretty tolerant of other fish species. I've kept mine with all types of fish, so no worries. Saxatilis pikes are generally 'less' aggressive than their Lugubris 'cousins'. So thats a plus!! With those types of tank mates though, especially the blackbelts, you might want to consider larger pikes. Or you could just move the fish around as they get larger!
