I was looking at plant geek .com trying to figure out what plants I have in my tank and it looks as if I do have one of the anubias but it says not to put the rhizome/rizome (?) into the substrate. Does this mean the little pot it came in that looks like the roots are wedged in there with some kind of cotton fiber? Should I take it out of that thing but not put the rootball in the gravel then?? Thanks in advance for any help on this!!
