I've got a 32g biocube that's a reef tank. It currently has a pair of Clownfish, a Purple Firefish, A Yellow Watchman, three Margarita snails, a GSP, and some small Zoa frags. I've also been thinking about adding an Azure Damsel. So, what would be a good shrimp to add in? I don't want anything that could break the glass or kill my other fish. I'd prefer one that is a popular choice for Yellow Watchmans in the wild.
