I have a plastic rock that I bought from LFS
awhile back, the tank in question has always been artificial 10 gallon.
Contains Tiger barbs/black skirts.
I've recently did a salvage job on my bedroom tank to get what was left of my plants. I then move them to this other 10 gallon with the plastic rock and remove all the artificial plants. All I have left is java ferns and some unknown grass plant which started the plague in my bedroom tank.
I would like to know how to attach the java ferns to the rock so it can root itself and grow.
I'm not sure how tho? String? Rubber band? Is the rock not suitable to root on?
