Duncan coral changes ?

[tbub1221]

Hi again , so i picked up a nice 2" duncan coral a few days ago , since its been home i notice a whole lot more color , and its tenticles are a lot shorter and stubbier , its moving a lot and iv fed it twice , it seems to perk up strait when it feeds so it seems healthy.
Is this all due to my lighting being brighter ?
it was under t5ho in a store so who knows how old tthey were but the light was easily 24" from the coral , i have 3w led about 14-16" away and i have 60 Degree lenses , so is my lighting to much ?
the light has no dimmer switch , should i look to a diy or inline type dimmer possibly . It is capable of day and night mode only .

something that I have noticed with my duncan coral is that it looks awesome and huge when my tank needs a water change. I think some corals just thrive off of dirty water. Don't take my word for it but the answer isnt necessarily your lights. It could have everything to do with water params

give it some time to adjust. It just changed tanks, it's not going to look spectacular right away

actually i think it looks quite well , just different , but i will continue to watch it and my water closely over the next week , thanks 4 the reply.

Edit: Im mainly scared that ill burn these guys up with these led's but i think it will be ok..

If they look good you're fine. Mine are more picky on flow.

 

[tbub1221]

ok , it is in a somewhat higher flow area ill try moving it if it comes down to it.

mine had long flowing tenticles for a while but it was under poor lighting and getting about 170 par. When i upgrade my lights (same exact flow) the tenticles got short and stubby at it's current 240 par.

i just sold mine, I think the owner of the colony who frag a piece for me had that under led's, not even sure if any lenses on it, and at the moment I took it from him it was on 24inch deep water, on my tank I place my frag on about 10 inch deep on my 25 gallons with MM led's, I start taking care of it by doing weekly water changes and sometimes every two weeks, this guy loves the spot feeding, I did it with frozen mysis, mine loves the flow as well, not directly but random currents coming from my PH and return, I don't have a overstock aquarium and I fed him every other day, and.... men all I can say is that I start noticing lots of baby heads and adult ones getting bigger, I actually dose a little CA every other day aiming for level, I don't think my tank consumes much Ca and I think that was extra, however, I saw a increasing amount of purple corraline on my rocks

How long did you keep it.

 

[joseayes]

I kept him for about six months

I'd take it off the sandbed. Duncans, like Euphyllia and other LPS can't stand touching the sandbed at times. I've seen them fall over and RTN from touching the sandbed overnight. I can see from the left picture that a couple of the polyps are indeed making contact (just an idea) Also, that Diamond Goby is probably dumping sand all over it when you aren't looking. Do you have to turkey baste it each day to get the sand off?

Also, they tend to get that shriveled look when they have been recently fed/overfed. I know this gets redundant, but I'd chill on the feedings. I've seen MASSIVE duncan colonies happy as can be where the hobbyist NEVER fed it! Corals eat fish poo and other things in the water column...

Just my experience...
I purchased 2 four heads of different color tone Duncan's last year, a hammer and frogspawn. I've kept them on the sand bed in a lower flow area. When i moved them to my new tank still on the sand bed but with stronger lighting and flow, tentacles were torn off from the flow. When moved to lower flow, they recovered imeaditly and continued to grow like weeds. They both were happy, extended nice and grew to 12 and 15 heads with many babies growing on all sides on the sand bed. mine like enough flow to keep them constantly moving but not intense flow that rips there tentacles. All my Duncan, hammers, frogspawn, etc. have been very happy on the sand bed (not where they are getting blasted with sand) but do receive adequate lighting in a medium flow area.

I understand this is not the same problem your having but, just my experience...
I purchased 3 small different color tone Duncan's last year, a hammer and frogspawn. I've kept the duncan on the sand bed and all above in medium flow. When I moved them to my new tank still on the sand bed but with stronger lighting and flow, tentacles were torn off and damaged. When moved to a lower flow area they recovered imeaditly and continued to grow like weeds, all have at least quadrupled in size with tons of babies growing on all sides.
Good luck!

 

[tbub1221]

Awesome, how many heads did it start as.
Why are you tearing down your tank ?

 

[camellia]

One was 3 and two 4 head. I'm not tearing down, I upgraded.

After reading Rskillz info (he has much more experience) mine maybe an exception as to the sand bed. Mine don't get sand on them but I would follow his advise & keep off the sand if possible.
