Sun coral melting?

[vetteguy53081]

Not true plenty of people have sun corals grow at the top of their tank for ease of feeding, I'm sure at a certain point they could be torched like other corals can from intense light

I was on the road. I should reiterate with my statement, as sun corals don’t form a symbiotic relationship with zooxanthellae and don't require the lighting that most corals require, which makes them more reliable on outside sources of food, such as plankton or smaller fish and Im basically stating that it is best to be careful when placing them in areas under direct lighting especially when new to a tank. Slow acclimation is the best way to ensure that the coral will stay in a healthy condition as again, they are Non-photosynthetic and should be placed in a spot where you can have access to easily feed it.

Sun Corals need moderate to strong water movement to thrive well. This stronger water flow will help the coral get the nutrients easier, and prevent growing algae on it as it appears is happening in the photo by OP.

Makes more sense. I just added the sun coral yesterday and to me looks more like the coral itself is dissolving, I haven't had any algae in my tank as my lights are freshwater, right now I just capped them off with a 2 liter and had put amino acids in with them, hoping to heal them up. I'm sure their needs weren't met at the LFS

Fourth day of direct dosing 2ml reef energy ab+ (amino acids) the sun coral is looking better and was able to feed two polyps a shrimp yesterday. The rest retracted when touched by the shrimp.
