Hidden cup coral questions

[Brandon103095]

Hey all, just set up a new 40 gal tank, on one of the live rocks I got what I can tell 2 hidden cup corals. My tank is cycling and yesterday the ammonia was between 1 and 2ppm. This morning when I woke up the corals seemed fine, tentacles were out. Will this cycle kill off these corals? Also curious as to how fast will they grow/spread?

Mine survived a harsh high ammonia cycle. They are very slow growers.

looks like trumpet corals and they should be fine. Corals don't care as much about the cycle as much as fish.

These guys are usually all curled up with the lights on but extend out very translucent arms in the dark. I almost think they might be non-photosynthetic.

Thatd be great those look amazing! But after having them a few days i can 100% say they are hidden cup corals haha. Happy with them too though!

Yeah i notice they are all out at night, i get to catch a glimpse before turning on my blue lights and they go back into hiding the tentacles haha.
