Thanks all for the compliments.
Jeri,
Yup, the clowns like the torch a lot. They stay there all day. The reason why I put the torch in the tank is making the aquascaping balanced. If I take the torch away, you will find a hallow for the aquascaping.
The tentacles are way higher than other corals. It's fine and safe, and give a clear view for the clowns.
Edwings206,
The yumas are getting huge. One of it is staying 20 months in my tank, growing from a quarter to 3.5 inch diameter.
Recently, I added a Viaaqua poly reactor and putting the rowaphos and rowacarbon. They seem like it.
