If you don't have epoxy then you could try super glue. I had a monti cap and acro fight for space and the acro won every time. I ended up transplanting the cap later since the acro would encrust over the parts of the cap it killed.
Not that it would happen for sure but I read on one forum that a person had a green cap and purple acro grow into one another and the cap ended up with a cool purple color that grafted into the green and grew like that from that point on.

I actually went out and bought the epoxy last weekend, and now I'm debating removing the whole cap [emoji23]
