The transfer will be easy. Get one of those rectangular plastic containers that they have at the fish store for handling fish (like this one
http://www.aquariumguys.com/lees-specimen-container.html). Use it to very slowly herd the fish into a corner at the top, bringing the container up under it. I keep a net in my other hand to help keep the fish over the container. Take the fish to the DT and transfer it from the container to the tank. I put my fingers in and slowly raise them until the fish is lying in my hand as I feel that transferring by hand stresses the fish less than a net, but many just use a net.
Wow - no need to worry about the "scalpel?" Are nets really that much worse?
During quarantine, I do QT water changes by emptying water from the QT and replacing it with DT water so that the fish in quarantine is acclimated to my DT water when it gets transferred from the QT to the DT.
I think I might do this, too, when a bit closer to transfer time!
