Sorry to hear about your bad luck with the gorg. Hopefully it will recover now that snails aren't knocking it into a bubble coral anymore.
Regarding the algae growth you mentioned earlier, you might want to try keeping the gorg in a dark area. Are the polyps extending at all in your boyfriends tank? If not, it could be the stress it went through, but it could also again be due to invasive algae growth. I still think that algae is the toughest thing about handling these non-photo gorgs in a mixed reef tank. Even if you don't see algae on the tank walls, it is still growing. Most of these types of non-photo corals don't have ways of dealing with algae as they've adapted to dark environments. Some people seem to be successful keeping these corals in mixed tanks. Perhaps they have managed to keep the flow sufficient to prevent algae from growing or perhaps they have low enough nutrient levels in the tank to keep it in check. I'm not exactly sure, but I do know that keeping them in the dark will prevent the algae from growing and afford you an opportunity to feed them and get their strength up.
