I have a slightly big GSP that is overcoming my Zoa. I want to trim it and maybe put it on the tank back wall.
Any advice on how to trim it and paste it on the wall??
If it's stuck to teh rock it's going to be pretty hard to remove and still be able to glue it to anything. You'll likely have to remove the rock and carefully scrap the GSP off the rock with a scapel. Hopefully you'll be able to get an edge of the colony lifted and can work it off.
