I want to buy a ceramic block letter M. I had this good idea for my father for his birthday, we use to live in Michigan and he just got a coral that encrusts and it has a blue base with yellow polyps and I wanted to get a block letter that we could put it on so it would grow over it. If you can help me find one I have looked all over the internet for one but can’t seem to get one that can go into the tank. Any suggestions on where to get or anything is appreciated. Here’s a pic to help
