Corals wont open

[ScubaSteve]

I'm with Denny here. Too new of a tank. Those rocks are sparkling clean!

How long has the tank been running?

You can try feeding the trumpet and brain to help them along. You can try some frozen mysis. Or go to the store and buy some assorted fresh seafood (clams, mussels, prawn, crab, etc). Using fresh caught seafood is better as it is typically lower in phosphates than aquacultured seafood. Give it all a rinse and toss the lot into a blender and give it a quick whiz to get a nice, stinky mush that corals love. Toss it into an ice cube tray and freeze it (canuckgod420 puts egg crate on a tray then fills the egg crate with the mush before freezing. He get's smaller cubes that way). Thaw a cube, mix it with with RO water and use a baster to feed the corals. Give them a tiny little squirt the let them sense it, then come back in a few minutes when they've got their tentacles open. They may open open at night initially.

Feed sparingly.
