My Tank Thread
My Aquarium Showcase
Then sounds like others have suggested- vermetidsNo, I do not see feather duster type things coming from those little tubes..
Those tubes are hard and seem calcified..
On my last big water change, I did notice string like things coming out of it..
I've had this tankfor a few years now, perhaps closer to 3 at least, maybe even 4?
A renewed interest has me motivated to get this tank back into tip-top shape.
I have plans to eventually start growing corals after everything is situated.. I figured I would first tackle the problem of these spike-like things first.
My second plan was to add additional sand (while slowly washing the sand in sections to bring out any leftover detritus trapped).
Help!
Also, what is that on my fan? Those are not standard tube-like things on my rocks, but its more of a patch of spikes instead?
