I just bought a used 72g tank and it is set up with fish and live rock. I will be moving it a week from Sunday and woud like to paint the back black. Is this a good idea since I will be trying to limit the time the tank is broken down? What is the best/quickest process for doing this? What type of paint should I use? Can I do it with a single coat or do I need multiple coats? I was thinking about black latex paint with a brush and using a space heater and halogen lights to speed up the drying.
