About 2 years ago I bought a 4-5 inch tall Kenya Tree leather and about 6 months ago it started break off into peices all over the tank... I now have about 20 Kenya frags growing all over my tank.. I would like to get rid of 90% of them and I am just wondering how this can be done safely... I dont want to pull out the live rock they are on because I am worried about die off... Is it possible to just cut them off at the base underneath the water? I attempted to cut one already and after cutting some sort of debris came out... Is this safe?
