I agree with the using a trash can, bucket, whatever, you could also just move some water to the bath tub to hold the fish for a while.ralphinnj said:Now move your 55, clean and or replace the gravel, clean and replace all filter media and re-charge with fresh water. Add in stresszyme and any other preparative water chemicals (e.g., pH adjustment, etc.) and let sit for a few hours. Move your heater over whenyou are close to making the switch. Make sure the temperature in the newly set up 55 matches the trash can. Once the 2 temps are identical, move the fish.
When you are done, you'll have a new trash can you can use.
