Should I make another altar?

Been thinking about making another but I’m not sure. I LOVE anything related to the ocean and I’ve been thinking about worshipping Poseidon. I’m limited in space, but with a bit of moving around, I can make some for another altar. I’m very much new and still researching, I already have an altar, for Aphrodite, but I haven’t fully begun any praying or offering since I kinda wanna do a bit more research before I do.

But worshiping Poseidon has been on my mind for a while and just want to ask here for a some opinions or advice. Should I just go for it and make one?
