I have not done much research on that species myself, mainly just Sirtalis Parietalis and Radix for now. I have heard that when feeding night-crawlers they can be fed sooner then if you feed them say fish filet (from a fresh fish market) or pinkies... Usually on fish/pinkies I would feed on every 5th day leaving a 4 day gap which would be feeding twice weekly but with enough of a gap she has time to digest and rid herself of the last meal. Over feeding can be a problem and obesity is hard for a snake to overcome if they aren't very active.

I wouldn't rely on this too much though, a second opinion would be nice.

I wonder though, most ribbons I have seen seem to be very thin? Is this the case with majority of them?
