I had a nickel sized bunch of GSP and it fell behind some rocks where I can't grab it but can still partially see it. So I bought another.
2nd one closed up after a few weeks in the tank. While the original opens daily. I tested the water and everything is the same except maybe around day 1 of the closure the salt hit 1.026. I did move a powerhead reducing the flow it receives around that time too.
Everything else coral, fish, inverts - no problems
Questions:
Does it prefer higher light, lower light, does it matter?
Does it prefer massive flow, decent flow, low flow, does it matter?
How long should I wait before writing it off as dead?
I know a lot of people will say - you are lucky it died before it takes over... but I really love the look so it taking over I see as a good thing
Thanks in advance
