How truly invasive are mushrooms/rodhactis?

[Eleni18]

Frilly greens.... ugh what a pia. You can't really cut them off easily. They have to be almost chiseled off. My rocks are not easily removed. I just end up killing them when they are in the wrong place.

Mine too! So how do you kill them?

Calc paste , but need patience - when kill one , new baby apears after few weeks ...took me abt year to get rid of

Weird, maybe, but shrooms die off in my tank. All other softies? Great. LPS? Great. SPS? Great. Mushrooms? Shrivel and die like if I left them on the table rather than in the water.

I've never tried this myself, but I ran across this video. Might help.

I gently scape them off with forceps.

I have green striped and red mushrooms. The green striped are more invasive. They have gotten to the point of budding off babies that wind up anywhere...like in the middle of zoa colonies. They will smother GSP. The reds aren't as bad but still like to creep up rocks.

Franks F-Aipasia does seem to work, but you have to completely cover them for a day and siphon out all the goo.

I have been blasting one of my main rocks with a powerhead to see if they release, but they just hunker down.

I'm hoping stingy hammers can keep them at bay.

Florida Ricordea or Rhodactis will be great, I’m a fan of Florida Rics from day 1 and as long as parameters are good they won’t pop off to find new homes. I had the FL ric garden in the front corner for years and years, they never spread like the other mushy strains.

Discosoma sp. will take over your tank if you don't control them. Rhodactis sp. and Ricordea sp. grow slower and sting less so are unlikely to take over your tank.

+1. To this post. My exact experience also.

These were incredibly invasive....

Try it with salt. Turn off the pumps. Take a handful of sea salt and let it ripple onto the mushrooms. After a while switch on the pumps again. Check salinity and if necessary replace some saltwater by R/O water.

Since I had to remove some "hairy" Rhodactis (indosinensis?) I have tried an improved method. Take a small plastic bottle (200 to 500 ml or about 0.1 gallon) with cap, drill a 5 mm/0.2 inch hole into the lid and fill some salt into the opened bottle, only a handful or two. Then fill saltwater from the aquarium into the bottle and close the cap with the hole.

Now you can bring the salt exactly to the targets very easily. Turn the bottle upside down over your targets and let the salt ripple onto your targets. At least with Rhodactis most of the discs to remove will be gone the next day.

Of course again you will have to switch off the pumps during and for a while after the procedure before switching them on again.

I hate my green mushrooms when the kill acros.
5 or 6 came in on a live rock.
They release and are growing in many places now in my 120.
Trying to pull them off the rock with forcepts is almost impossible.
They sting and kill any coral they touch, so what did I do?
This is going to be controversial but works well in my 120.
Take a 3cc syringe and a 1.5" 20 gauge needle.
Fill about 1cc with 34% h202 and inject the shroom with about 1/4 cc.
The shroom will turn brown right away.
Wait a couple minutes and grab the stalk with forcepts and they remove easily.
I do 3-4 at a time.
Never had an issue with the h202 affecting anything else in the tank.
I am not removing all of them because I actualy think they are cool to a degree.
However when they get close to other corals they have to go.
I have removed around 20 so far and have twice that many left, lol.
Note: I only remove 3-4 at a time no more than once a week of treatment.
