Duncan Frags

[rustix]

I recently got two Duncan rescue frags, one with three heads and one with a single head. The single-headed one's doing fine, eating and all that. However, the three-headed frag's tissue keeps receding and it won't take food. Its tentacles and body are pretty fat and bulbous compared to my other Duncans. When I got the frag, I dipped it in Lugol's solution, cleaned off some algae, and inspected it. The tissue was already receding a bit back then. My tank's running at 78 degrees, pH 8.15, Alk 3.5 meq/l, No3 0.5, Ca 435, Mg 1395, and Po4 0.

Looking for some ideas on where to go from here, or if anyone's had a similar issue with Duncans. Any clues would be appreciated, thanks.

I'm no expert, but I've had some luck with my own Duncan - still a lot to learn, though. Have you thought about giving it another dip, maybe with Bayer Complete this time?

[rustix]

Thanks for the suggestion, I'll definitely look into doing another dip, maybe with Bayer Complete, see if that helps turn things around for the 3 headed frag.

A visual would be super helpful.

My first foray into stony corals was with Duncans, back when I was still figuring out algae control. I've found them to be pretty sensitive to algae irritation. I had a few heads disappear, but after cleaning the exposed skeleton with peroxide, some of the polyps actually came back. Hopefully you'll have better luck with yours.

Here's what I managed to capture - the 3rd head is now on its way out.

I'm still a bit new to corals but having some luck with my Duncan, might be worth considering another dip, maybe try Bayer Complete this time around

The coloration of the polyps looks good, that's a plus. I'm thinking maybe it's a light issue - too much or not enough. Tissue degradation can also be caused by something stinging it, that's my guess. What's the neighborhood like around the coral - anything growing that could be bothering it?

[rustix]

It's getting around 125-150 par, and there's a Sinularia nearby, along with my other Duncans.

Looking for a Bayer Complete dosage for dipping - what have you guys used in the past?
