I have 2 GBRs in my 55 and they leave my HC alone. My problem has been mylasian trumpet snails uprooting my HC by just moving underneath them.
My solution was a very small amount of super glue and an equally small rock. Since i've done that, none of my HC has floated and will hopefully give it time to grow roots.
