You can also set their rock in a high flow area . They won't like it and they'll try to move out of the flow as they do so they leave bits of their feet behind. Just, leave the rock in high flow for a couple of days and move back to normal area. You'll have several new ones or you can just use a razor and cut of little bits of foot they will also grow into new shrooms fast.
Like rothchyld said they can be weeds
Just how do you get mushrooms to take off? I've got a few on my LR and they seem to look sick most of the time. They're not dead but I have had them for quite awhile and they don't do a thing. What do I need to do?:help:
I'd say my waters on the dirty side, but I do a 10% change every week. Tank itself is a good 7 seven years old. The parameters, I don't know haven't check for a while. Last time everything normal except hardness which was low, but not too low.
