1. flowerpot. goniopora. Hard to keep alive in our closed systems.
2. a deflated tree coral. I'm not sure if the orange variety is a kenya or not. They are easy to grow to the point where they can be viewed by some as a week, but that orange coloration is much prettier than the average kenya.
3. a brain coral frag. There are two types, favites and favia. That is a favia. You can tell the difference due to the 'walls' of each head not sharing. Favites share a common wall.
4. Jasmine polyps. A simple clove polyp coral.
