Personally I use mostly tubs, but I do use a glass tank for a backup qt. the tank takes much more monitoring and work. But it can be kept up to standards if you keep on it and set it up properly. As long as you have it setup properly ( pretty sure someone linked the 20g setup thread already?) I don't see an issue.

Im so glad to see how pip is doing! Awesome job getting pip what he needs! We need more pics!!
