Well it's been since sunday, and here is the coral now:
Opened up alot more and the tentacles seem more full on average. We also got it to eat some salmon today. I'm going to try some fresh shrimp next.
I haven't been leaving the koralia powerhead on all the time, I randomly plug it in and unplug it, but I think I will put it on a timer, since I think the powerhead being on permenantly seems to shrivel up the tentacles closest to the flow after a while, but if I give it some breaks it seems to be best of both worlds (blows waste off, and doesn't over stress tentacles).
what do you think?
