Flippin...............
I have not heard of it being called that, but it is very possible!! I will do some checking and see if that is one of the names it goes by.

I maintain over 100 tanks and do resale from my home!! The trick to getting plecos to hold still is this.....
You need to let them attach their sucker to your finger. This makes them feel secure as tho they were in the aquarium!!
If you look closely at thepleco pics you can see all but the L200 is attached to my finger. The L200 being a little smaller did not require this!!
