Species Game

I have an answer that fits (although it may be like your spiny eel, a perfect fit - but wrong). How about the Madagascar clawless gecko (Ebenavia inunguis)? I think it meets all the criteria, but I couldn't get close without your manicure clue.

Nope, it is not the species i'm looking for i'm afraid, though you are relatively close taxonomically.

As I seem to have killed yet another thread, i'll try and revive it by posting another clue:

Other members of this species' family are very common in captivity, particularly in the pet trade. However, this species is more fossorial than most of it's relatives, one of the factors making it less commonly kept.
