Not going to get a goby because I’m getting a fighting conch. Gobies become territorial and stick near to their territory once established which makes the fish a useless utilitarian fish after a while. Not going for a 6 line because they’re known to be extremely aggressive to new additions and just in general and I’m not getting a melanarus because I’m not going to get a bigger tank because I honestly don’t want and never have considered going any bigger. Plus, it’s expensiveI Really think you should consider a Diamond Goby. They are gorgeous and they clean yohr sand bed and keep it free and clean and they look like dragons.
If you do go wrasse. Go for a 6 line or a melanarus (will eventually need bigger tank)
