Does anyone use Visions for their corns?I have larger visions that I heat with dome light spot bulbs and they work great.I'm thinking of getting rid of my ARS rack system and switching to #221 vision cages for my corns.I have one adult in a 20 long tank right now and I like being able to watch her cruise around in the evening,instead of having to slide out a tub to see them.How well do the visions work with UTH? I want to stack up 6 #221 cages and heat them with flex watt,to try them out.I have a 6 plug Johnson therm to run it with.
