Last Friday I picked up a small, single head duncan to add to my nano. It is getting gentle flow below the outflow of my filter. However, it is only extending tentacles on one side of it's oral disc. Is this a sign of too much flow on one side, or a different issue? Sorry I can't take a better photo, my lights are mostly blue and I have no orange filter.

Could be amongst other things.

Can you post your parameters?

What are your parameters and how long have they been at “these” numbers?

Although pic fuzzy, light seems a little bright. I run mine under moderate lighting and flow and feed them mysis shrimp 2x a week
Assure salinity not elevated , calcium not low and phosphates not elevated

In order for the pic to not look completely washed out in blue, I passed my finger over the lens to briefly get a "clear" shot. My light is not as intense as the photo suggests.

You need to know what your parameters are. Without a test kid, you are preparing to fail

What light are you using?
While waiting for kits, you can sure take a water sample to a store that does NOT use Api kits and have them test your ammonia and nitrates and compare readings- then you'll know where your levels truly are at

Under moderate light and flow, these are mine:

Using a ReefBreeders Pico v2 on about 70% blue and 20% white, 8 inches over the top of a 30cm high tank.

The nearest store is a 50 mile drive and I'm pretty sure they use API.

Consider investing in Hanna or salifert brand tests

Those settings are less than I use for my 1 gallon pico tank. How many gallons is your tank?

This is a .9 gallon display with a reefbreeders pico v2. 80% blue and 20% whites

if you really are keeping up with water changes at that level and your not having algae problems, feeding stupid heavy, your parameters are probably fine. Test kit would be nice to have, but that line, what are you parameters, makes me think of the seals squawking in finding Nemo lol....I imagine its a nano if your changing 40% water a week, insure your salinity is ok, and not a bad hydrometer or a out of calibration refractometer.

My question would be how long have you had it, and is it a flow issue, feeding will strengthen them up too and make them deal better with flow, if its new from a shop and hasnt eaten in a while

just read the OP again its pretty new feed it some ant sized pieces of shrimp or raw tuna 2 3 pieces, 1 at a time and see if that plumps it up and gets it less annoyed with the flow, should be fine tho, not the prettiest looking stem but hard to tell in the photo, its a Duncan not too fussed about too little light and doubt you have too much, flow can make them wonky especially new small unfed frags from stores, in the future try to find hobbyist friends and avoid stores they charge wayyyyy too much for inferior products and often times have non-hobbyist or relatively new working in there

If you wanted to get a better photo. You could either turn the lights off and get a photo, or turn the blues off on your light to where it is just white lights. Do you have any other corals in your tank? How are they doing? Also how old is your tank?

-Tank has been running since late January
-aside from light dusting on thr sandbed and glass, no algae
-I top off evaporation daily
-I recalibrate my refractometer before every water chsnge to ensure accuracy
-I feed a small amount of frozen mysis and pellets once or twice a day
-only flow is from a oversized Fluval HOB filter which creates a moderate to gentle flow (rated for 30 gallons, I think)
-while I do generally broadcast feed, I spot feed my only fish with a pipette and have successfully fed the duncan and zoas
-when I got thr duncan from the shop it was covered in hair algae; did a reef dip and scraped the hair algae off the frag with a metal pick (currently algae free)
-photoperiod is 8 hours
-salinity is generally between 1.025 and 1.026
-I suspect nitrates and phosphates are low based on my feeding and water chsnge habits

Good Questions, really would like to see the stem better, almost looks like it might be tissue less which wouldn't be good, but would probably be like that from the store if its been 5 days, pushing it to an unknowing noob maybe, possibly from an unknowing noob

Yes, there is no tissue on the stalk, it is encrusted in coralline which concerned me, but I was able to get a feeding response ao had hopes it would recover.

feeding is a good sign, give a little shrimp every 3 days and see what happens normally the stems have a flesh to them so that's strange that it would have Coraline growing on it, unless it grew onto skeleton can google image duncan stems to see, normally a nice green have seen sometimes white or brownish too, I tend to avoid those kinds but may be healthy
