I don't necessarily know for sure either, so I try to error on the safe for the fish side and give them the best chance I can. Logically it seems like wet plastic would be less of a detriment to the mucus layer. Dry anything would probably not be too good. I know that in doing studies and other measurements a "trough" is often used. I would assume that it is plastic, but I don't know for sure. Probably makes it easier to measure though.
I don't know that there is any best way. Just do the best you can.
