I like shoals of small fish in my tank. Have tried to accomplish this with anthias, but I always seem to end up with a trio ...... not much of a shoal. Plus it gets expensive. Being a learning organism, and recognizing that doing the same thing over and over again in the hope of a different result is stupid, I decided to take a different approach. With my current 450, I have loads of space, so I decided to try the whole shoal thing with damsels instead - specifically the relatively less aggressive yellow tail. I now have 13 in my tank as shown in the photo (well, that's not all of them). If this proves a success, I shall get another 20 or so (maybe even go crazy and do azures).
