Are you on our email list?

We've decided that we will send out a weekly email to let everyone know what fish and other livestock we received that week, so you can make your weekend plans. If you would like to be included, drop us a PM and we'll make sure you don't miss out!

This is a Blue Linckia Starfish that we received this week. They are completely reef-safe, and a vibrant addition to the cleanup crew of a large, mature (at least a year old) aquarium.

We have a nice, healthy Foxface Rabbitfish on the smaller side available in the store this weekend!
