Hardy coral that lives on low lighting?

[PFisher]

I have a what most would consider low lighting (50W of NO fluorescent and 60 W of T5s over a 33g) and the mushrooms that I have in open areas grow like crazy, there are even a couple that have found homes in shaded areas that are doing fine. They are not growing as fast as the ones that get more light, but they are still growing. So I would feel comfortable suggesting mushrooms to you, just pace them high in the tank. But as Bob stated, don't expect spectacular growth.
