Exactly, Hahaha.
I keep my suns and balano (poor man's dendro) in a 5.5g pico with some gorgonians. It started as a 2.5g setup, but I've had issues with leaking tanks twice already, so everything is now in a 5.5g. Probably better in the long run. The LR and substrate though has been running since August last year. I've found...
1. flow, flow, flow! I've got two Rio 90s and an Aquaclear 50 modded refugium.
2. I feed everyday, but I have what I call heavy feedings and light feedings
3. Variety, they love eating different things
4. Temperature, my reef is also at a cool 76
I also use the tupperware method. My first sun coral is still a bit problematic, but it was my first one and I didn't have the experience I have now. It also had about a month where a cleaner shrimp was stealing food from it's polyps, so while I thought it was eating, it was the cleaner shrimp that was actually eating. I will tupperware that one every once in a while to give it a boost. Today it gets a tupperware feeding. It's smaller than my other suns and it was the first sun that my LFS and I had ever dealt with, so mistakes were made. You learn, you experiment until you find a method that works for you and that results in happy corals. I'll post some pictures of my suns in a bit, but in a different thread.
