I purchased my center piece acanthophyllia from aqua SD. However, when I received it the edges looked receeded and the coral hasn’t yet opened. AquaSD tells me the edges were trimmed to remove old die off to make the coral more presentable. I Have photos from the vendor from before it was...

Hi all. It's been 2-3 days now that my yellow tang is not its usual self. It is hiding in a rock most of the day, not even coming out to eat. All the other fish seem OK, water parameters are all normal (tested yesterday) and there seems nothing else wrong with him. I've had him for about 4...

My show fish has seriously hurt itself. It scrapped itself on both sides of its body and face. Perhaps it got stuck going through an opening in the live rock too small for it. It's now hanging out in the middle of the tank listless. Im concerned it will die of a baterial infection secondary...

This is my first time running a QT system. I did a lot of research showing that I need to maintain a level of 1.5 - 2.0 ppm copper. However, I was just informed by someone saying that using Cuprion (which is an Ionic copper solution) I need to maintain a .15 - .30 level for therapeutic level...
