While I keep a number of crab species, I would keep careful watch over those. Very very suspicious looking. Many like that tend to be..... Opportunistic. With the opportunity and the hunger, they tend to do what they want. But congrats otherwise! Such a great hobby! The water change can be your best friend!

I like progression, good work.

And I share the same concerns as FlammySnake. One rule of thumb is that if it has black claws, or black tips...run. I have a hitchhiker who made quick work of my zoanthids before I could figure out it was him. At least one of them looks like a xanthid species, which are notorious buttheads.

are you cycling the tank with that blue chromis?
