TonySpumoni95 posted a topic in Coral ForumIf you read the title, I am not paraphrasing. I've had this duncan colony for roughly 2 years, and for more than 6 months, this coral has not opened or even come close to fully opening during this time span. The coral has been through two different tanks (a jbj 28g LED nano cube and then transferred to a jbj 45 gallon). I've tried changing light parameters, water parameters, positions, flow (all within large spans of time because quick changes can shock the coral) but I've had little results. The closest I've gotten to "open" was a slight protrusion from the skeleton, with a few tentacles showing up (Happened after a water change, so there is something in the water that is bothering it in my opinion.) I've also noticed a few aiptasia anemones appearing, so I'm wondering if one is wedged underneath the coral and is stinging it. The flesh of the coral still looks good, full neon green color. I'll post a photo of the colony a little later, and I'll list my current parameters (Currently high because I've been changing my dosing amounts in accordance with the duncan, only been doing this for roughly 3 weeks), as well as my tankmates, equipment, etc. Any help would be appreciated, and thanks for stopping by.
