Coral update! Along with an astrea snail, I got an assortment of corals for $25 each! I’ll post pics once they’ve opened up, but four of them I think are forms of leather coral, and one is some kind of zoa. It’s hard to tell with petco’s vague labeling. One of the leathers refuses to open up (and I think the frag plug it is on has a little aptasia on it but hopefully the peppermint shrimp will do the job) and the zoa has some sort of algae growth and hasn’t opened all the way. I’ll post pics once they’ve all opened for IDs. Also, I think my margarita snail is dead. He hasn’t moved since I purchased him. I flipped him over today and he’s just tucked in his shell. I’m concerned.
