It's probably damaged from the fall. When a coral gets
punctured, it can't build up as much pressure when
inflating, and so will not fully inflate until it finishes
healing.

Hi All,

I bought a Capnella yesterday for my Nano reef tank. I initially placed
it half way up the rock work but it fell off so I then put it in the
substrate. As the day progressed it started to bend in the middle.

Yesterday evening I fed the corals with some phytoplankton including
this one.

All of today the Capnella has been bent almost in half and has been
clamped up. I've moved it up the tank again in case it relates to the
amount of light. The tank is a 15 gall with 3 15W flourescents.

Do you think I'm on the right track or should it be less light rather
than more? Or is it a problem with the coral itself (possibly got
damaged in the fall)? Or is it an acclimitization issue and I need to be
patient?

Tank parameters a-

Temp 26.6C
Sg 1.026
pH 8.4
Alk - higher end of normal (Red Sea kit so doesn't give specifics)
NO2 0
Ca 550 ppm (which seems a bit high to me)
NO3 High Range 25 Low Range 5
PO4 0.1

All other corals, including some others added yesterday, are doing fine.

TIA
Gill
