So little back story, tank is 1 1/2yrs old. I was incredibly slow and patient with stocking. Had a handful of frags and then the tank crashed during one of the power outages last fall in California. Lost all the corals and one fish.
The crash was tough on the tank, but everything (including the following algae bloom) cleared up within a few months. I waited another month or so, put two acros in, waited another month, and got a battle box.
The corals from Adam were added about three months ago, started dosing for ca/alk about 6 weeks ago. Everything looks good, some corals color and/or growth are better than others.
The frag in question is one from the battle box. It encrusted for a bit then stalled, but otherwise no change for a bit until these weird balls showed up the other day. I have no idea what they are, never seen anything like it.
I haven’t completely ruled out bugs, but it seems unlikely to me. All corals came from trusted sources and dipped in a massive dose of bayer. The balls don’t seem to move at all either, they are stationary on the affected polyps. No other corals seem to have them.
Any ideas?
