Good news!!! I just spoke verified with the owner and the 30% off on Friday and the 25% off on Saturday and Sunday will apply to ALL livestock - so that includes all inverts, corals, fish, or anything else living in our store that lives in saltwater and is for sale. We don't have many inverts right now, just hermit crabs and sea stars so far, but if that changes I'll be sure to let you know here.
