i acclimate by putting the specimen in a fair sized tupperware container with about half water from the store.

then syphon from the main tank through some airline tubing and have a slow drip into the tupperware. i use a little adjustable plastic valve that lets you regulate flow, but you can also just tie a knot in the tubing to create the drip

once it fills i drain about half the water in the sink and repeat the procedure. once its full again hell be ready for his new home.

not a bad idea to cover the tupperware aswell incase he decides to jump
