Refresh my memory on your system. How long has it been up and running?
Corals are funny things. It mainly depends on your system. I have SPS
that grow faster in my system then my Zoas and mushrooms do. It all depends on your water parameters and your lighting. Flow also has a lot to do with it.
For soft corals a toadstool leather will do well and grow nicely in a year. Mushrooms are always a safe bet and are hardy. Zoas as you mentioned will do well in your system and grow nicely. If you are looking for hard corals be they SPS
you have several options. SPS
- Montipora Digitata, certain acros (pm me about this) and Montipora Capricornus will grow fairly quickly. LPS
- Frogspawn (you have this and it may grow quickly for you) trumpet coral, some bubble corals and fox coral tend to grow quickly.
Hope that points you in the right direction.
