Caring for a Duncan?
 

I have an aussie duncan frag. What do these prefer for light, flow and feeding?

Thanks in advance.

I have mine at the bottom of my tank. It likes low flow. And I think they adapt easily
as, I have moved mine all over the bottom. Just to see what it liked better. Did not
make a difference. As for food I feed phyto, brine, krill, mysis whatever I feed all the
others. I have never target fed it. Not sure if others do.

I have mine in the botton third of my tank. Medium flow. When I first got it, I used to feed it mysis once or twice a week and had incredible growth. When it was injured by an Hydnapora I feed it every day and it completely recovered.

Now that I have fish, I feed it daily with the leftovers of a mixture of mysis and brine that is left in the cup after feeding the fish. I no longer target each head as there's well over 60 of them. I just use the turkey baster and squirt it all over. I don't think any of the different feeding methods has done any better or worse. Sometimes it has gone 2 weeks without target feeding.

Hope this helps.

medium to low flow. It looks better to me in low flow but it will adapt to just about anything. very adaptable to light within reason... photoacclimate if necessary. feeding is not necessary, but it will grow more slowly. feeding just increases growth. Maximum feedings of once every two days. this really boosts growth like you wouldn't believe. I've fed mine mysis, krill, chopped up shrimp, silverside, cyclopeeze... im sure it would eat just about anything you give it. variety probably doesn't hurt either.

I have mine on the top of my tank, 18'' under my 20k 400w metal halide. its growing fast. I have mid-high flow, IMO I think with low flow it doesnt look that nice because of the tentacle extention(too long) it loss it colour (metallic green to brown) that is only me tho.

Thanks all. It sounds like a fairly low maintenance critter. I had run out of epoxy so I had just stuck this guy in a crevice in the mean time. Now that I have some epoxy I have to figure out where to install it.

The frag I have has two main polyps with a baby polyp on the side. It looks like this species grows by adding polyps as side "branches". Will it form additional attachments to the rock or does it grow like cauliflower?

Mine is really fussy. It will be happy in one spot for weeks, then decide it's not happy anymore, so I have to move it, then same thing. It must have itchy feet. :lol: Generally it likes low light, low flow.

So does unhappy mean it closes up?

thanks, good stuff.

Yes, or partially closes up, and makes itself have really short tentacles. I don't feed mine, but I should try that.
