Healthy Tank?

[Craig16]

Just a quick question, my tank has been set up for 3 years (yes I am still a newbie). Tank has crushed coral base, a few rocks for cover, with a Domino Damsel and a False Perc. The question I have it, I have about 100+ feather dusters growing in the tank, is this a good sign? They are growng really fast too, they are all over the rocks and the crushed coral.

any additional growth and life that you can find on your liverock or in your tank is a good sign. Except for maybe some of the non-reefsafe stuff you might find. But usually the things that grow are inverts and i believe if things were bad they'd be the first to die.

I'd say its a good sign your tank is doing well. :)
