So....sun coral??

[stevo01]

Sun corals are one of the easiest and hardiest corals to keep out of them all. I've kept them on and off since 2003 and as long as you give them a bit of flow and feed them a couple of times a week they will thrive.
The info the guy in the first video was giving out was complete overkill and making loads of work for himself, a couple of minutes to place a few bits of meaty food on the polyps with the pumps off is all that is needed and you don't need to get every single polyp every time.
As for the video with the goby, i would put money on it that the fish was already injured and dying, i have a small pair of clowns that are hosted by my orange sun coral and it's never attempted to eat them ever.
They are so easy to keep that i even have babies spread all over the tank that appeared around a year ago, i never feed them and they are doing fine and must get their food from whatever is floating around the tank.

Thanks! I hope it works out.

Woah, they can eat fish? Maybe that's another in my tank then!

They can actually catch smaller food. I never fed mine (acquired last year) except on the first few days to train them opening at specific time. Just snap this picture (5.50pm local time) where they just start blooming for the day. Usually they stay opened till next morning. Not sure what triggers them to open daily without food intervention. I might be lucky having these specimen, have popped up a few heads since.

Just curious, I have a 20gal with two clowns and two snails. I have yet to have any corals but I would love to start a nano. Would this be a good coral to start with since the lighting doesn't really matter as well as eating basically the same as my clowns and are hardy? Params:

Ammonia: 0ppm
Nitrite: 0ppm
Nitrate: 0ppm
pH: 8.3
SG: 1.023

I can't check for calc/alk/mag/phosphates etc because I don't have any test kits for it but I won't be adding corals for a good couple of months since I have a large freshwater build going on. I would love to get a start on corals by knowing what I want/need for them. Thanks!
