Duncan tentacles short..

[RacingTiger03]

I've had a duncan in my tank for a couple months, and the last 2-3 weeks its tentacles have become very short (not like before when they were 1-2"). Now my duncans just look like oversized zoas lol. Does anyone know what determines tentacle length of these guys so I can get them back up to the 1-2" range? Everything else in the tank is doing great including my RBTA *shrug*.. and the duncans appear to still be doing great other than that. Good coloration and eating well.

Have you changed anything? Lighting, flow, dosing, salt, etc?

Have you been feeding it alot more?

same salts, I did add one 22watt T5 bulb... I have started dosing limewater to keep things stable. I have been feeding it less as well. Just two days ago I moved it to a higher flow area of the tank hoping that may encourage tentacle expansion (similiar to zoas) and so far no luck with that, but i plan on giving it a week of that.
The second reason I moved it is about 24" away I added a stylo to the tank, and thought it may be battling a bit with the duncan. though the duncan was downstream from the stylo, and I run carbon due to a RBTA in the tank i don't think that is very likely...
thanks for the quick responses guys!

Anyone have some advice on how to get the longer tentacles back? Should I start feeding it more often again? Take the additional light back off?

I would leave it alone and let it adjust.

My Duncan acts up every so often. i have had it for over a year and sometimes it will only open half way. Just leave it alone and it should go back to normal.

I really have to learn to work on my patience when things aren't how I like lol. I guess I was just worried that it may be getting attacked by my stylopora. Hopefully it will get back to normal length before too long

 

[subielover]

Yup, that is one of the biggest/hardest things to do in this hobby, that is keeping our hands out of the tank.

mine is only high flow growing really fast but short tentacles.

They are tuff. I had chalice frag land on mine and took out 3 head completely. Within a month they where growing back. My duncans where the very first coral I ever got over a year ago. They have been in three different tanks, me learning about the hobby and they are still alive. My duncans and my frogspawn are the only things I have left from the begaining.

They are very sensitive to light change, mine shorten the tentacles every time I change the bulbs, then take a month or two to get longer again. Also I have seen phosphate issues cause the same thing, it seems to be a reaction to somwhat moderate changes in environment, and they will stay that way till you get the conditions corrected and stable for a while.

I have started dosing limewater to keep things stable.

Are you sure that this is making things more "stable"? When I dosed limewater, it caused my tank to swing wildly (due to the way I dosed it primarily) All I am saying is be careful dosing, it can hurt more than it helps sometimes. I eventually got a calcium reactor which has helped me keep my tank infinitely more stable than when I was dosing!

Pretty sureit is staying more stable... I've been really careful about how I dose. Less than a 2 liter a week and still doing weekly 20% wc. My corraline and coral growth have really taken off since dosing and my parameters are much better than before. I had a hard time keeping my alk high enuf.
