Thanks everyone, hopefully I'll continue to grab monthly photos.
I used a good amount of super glue gel for the monti.
I put it directly on the frag and put it in a small cup of water.
This harded the glue a bit. Then just stuck it on the overflow wall.
I work it back and forth until I feel it harded put. It was also a small frag.
I'm thinking of adding something else on it also.
