I have compact fluorescents that came with the tank. Parameters seemed good last time I checked a week ago. And I didn't really acclimate it well :/
I put it under lower light to see if that would help. Sorry if my info isn't that great I'm still pretty new lol
Thanks for the really helpful info! My tank has been set up for a little over 2
Months
It looks like Trachyphyllia geoffroyi (Open Brain) to me. I have two varieties and they do fine in my 28g biocube.
Just give it time with low flow and low light as mentioned. You should start to see it expand more and more every day till it is fully acclimated.
