Too many mushrooms?

[WarrenG]

I have about 80 red/brown mushrooms growing in various places throughout my 90g reef tank. I've had most of the live rock for more than 10 years, and the rest of the rock came from Hawaii almost 20 years ago. As long as the mushrooms are not touching LPS or SPS, is there any reason to be concerned about having so many mushrooms in the tank?

Probably not.

Some mushrooms can get agressive, such as hairy green mushrooms. You need to keep a close eye on that variety before it does start a battle with nearby corals.
