Not trying to offend, just throwing in a little personal exp. I am a little inclinded to diagree with the PC not being enough. my 29g tank has only 1 Coralife 30" PC fixture on it, and my frogspawn was about the size of a cantelope melon fully extended (I say was because I just moved him to my 125g with my new T5's, I had to split the skeleton to make placement a bit easier). I didn't really directly feed it much...at most once a month, and I didn't really feed much in the tank, since it wasn't that heavily stocked. I know he pulled food out of the water column, but he couldn't have pulled that much since there wasn't alot to begin with....specially with a tailspot, firefish, perc, and my watchman (food went in and it was a battle royal...everything was nutz darting around grabbing food
). At most I only saw him grab 1 or 2 pieces of mysis at a time, and not really all that often either.
I don't disagree jackri that PC is really the bare minimum for a coral tank, but I don't think it just being a PC light was a direct influence on it's poor health. Rather that the lights weren't changed on time (every 6 months) and the specturm you had left wasn't meeting it's requirements.
Had I known more earlier on I would definately have gotten T5's. The more PAR (usable light by photosynthetic beings) you can put in your tank, the better off you are....I would have gone MH, I just in no way can afford the cost of MH/HQI fixtures and ballasts or the monthly electricity bill for the 125g, so I went with T5's. I am really not planning on doing anything that really requires MH/HQI, so for me it's a moot point. Of course like anything in this hobby that is subject to change without notice
. I honestly think once you nurse it back to health it will be just fine, mine always has been, and I only had PC.
Either way you look at it, plenty of light, and the occasional feeding, and you're frogspawn will end up much happier and you will be much happier with it. Please keep us updated on how it's doing, I know I would be interested to know.
If I am wrong here, please let me know. I am just going by what I have learned, seen, and personally have done.
