polyps are super simple. 1st off if they are only a couple days in the tank, don't sweat it. It usually takes a few hours to a few days for the new critter to realize someone has pulled the ole switch a roo..As a note, you should check your alk
. make sure they aren't too outta whack. Dunno what else you got in there, but a PH
of Min 8.0 to max 8.3 is a good target. Also, alk
min 9 dkh
to ~11 dkh
or (Some say 12 - 15) though NSW
is about 8. (Course this isnt NSW
; ) More testing just in case, but in reality a week to two of being closed or erradic behaviour is just part of acclimation.
