Thanks jugger... believe it or not the only real expenses have been my clams, and beyond that many have been frags from members of my reef club.
Here is a pic from I think April of my fungia. Regarding indicators of health, color is not really a good one, particularly with fungia. There are many varieties and colors of corals in the genus fungia, including a new orange variety I've seen recently for $120 at a LFS. Look in Eric Borneman's Aquarium Corals book and he has many photos of different varieties. Just because yours is green doesn't mean it's less healthy, it's just a different variety or species.
A healthy fungia should have no exposed skeleton. In the picture here you could see that the tissue is pretty well extended and the tentacles are flying around. Sometimes, usually during the day in my case, it is shriveled up, which is normal. It's different with every coral, but you should see this continuous ebb and flow of opening and closing over a 24 hour period. Regarding color, when I first got it it was a deeper pink, but it has adapted to the lighting it's under and grown more of a lighter pink. I believe the pink fungias are from shallower water, thus having these pigments as a result of receiving more light. In my tank it's adapted and has grown quite a bit. Just because it's lighter or darker has little indication of health. Corals will grow under different intensities and wavelengths, adjusting their pigments and thus their appearence. This is called adaptation, as us humans have done. It doesn't mean Brazilians are healthier than us just because they have a tan, that's just the way they've adapted to deal with the sun. Send a pasty white Minnesotan to Brazil, or vice versa, and the same thing would happen
Do you have a pic of yours?
