Mesenterial filaments? Just feeding?

[PSam]

Recently noticing mesenterial filaments from my acros. iirc, it can be a normal feeding reaction, or, defensive. I’m assuming (hoping) that it’s a feeding response. But I guess I’ll also assume that what can be a defensive reaction in nature may be an indicator of stress in an aquarium?

to be noted, was using prodibio (bacs, C, aa's) for the last 4 or 5 months - started reducing that and now doing very light doses with Ultra since ~ 2 weeks ago. Never noticed the filaments before, only with the recent additions of FM. No TN that I can see, polyp extension is fine, nothing to indicate anything out of the ordinary, other than that the MF's come out shortly after I dose.

Any ideas? Just feeding?

howdy neighbor

imo it's just feeding, i notice this when when feedings rods, pappone, and other "juicy" foods.

[PSam]

Well, howdy, howdy. That's what I was thinking at first, but I've never seen it to this extent with Rod's, nor with the prodibio, so I started thinking that it may be a reaction to changes over the last couple weeks. I'll try to go snap a photo...

i did a water change with cooler water and a urchin in my sump spawned after being exposed to the water, and my acros mesenterial's were out in full force.

[Canarygirl]

I had this happen the other day after I messed with a frogspawn, trying to mount it to a rock. It was pretty shocking to see all those strings hanging off my acros. I've never seen this before.

[PSam]

So, thats 1 chalked up to feeding (F&E) and 2 on the board (twon and canary) for what sounds like defense - that's why express a little concern - if not feeding, then it is stress / defensive due to changes in tank?

Canarygirl - you run zeo, correct? This is happening after I dose FM ultra - have you seen anything similar with zeo (maybe food or AAHC?).

[Canarygirl]

Yep, I run zeo but I've never had anything like that happen after dosing zeo supps. What kind of supp is the Ultra? Is it their amino acid product? Hmmm, I've heard of the odd person having negative results when they happen to get a bad bottle of something (whatever brand). I wonder if you got yourself a bad bottle of Ultra....?

[Flint&Eric]

not to make it even more difficult but.... i'd consider twon's both. spawns are a great source of food given there is enough water volume and export that it doesnt foul the water.

yeah, i only changed about 15 gallons in the 180, with 45g sump, so the only thing exposed to the cold water were two compartments in the sump. had i been camera toting it would have made a great picture seeing the urchin releasing brown stuff into the water.

Chalk one more up to feeding. I've got some pics way back in my gallery of an Acropora catching [in slime web] Cyclops-eeze which it inhaled. Along with the slime-web, there were some significant messenteries out.

I also recall seeing them come out during one of my interceptor treatments.

[PSam]

middletonmark - i saw your photo in all the past threads i searched - awesome pic with the cyclopeeze. but there you go with that 50/50 i keep finding lol - one time it's feeding, another time it's from interceptor (assuming that was irritated)

Canarygirl - yeah, i think the response is to the UltraMin S (aa's). I don't think it's a bad bottle, expiration date on bottle is a year away, but furthermore, everything looks fine. just curious that other aa's or foods haven't caused a reaction like this.

[twon8]

i get them to some extant on some acros when I feed mysis/bloodworms mix.

I'd say the interceptor may be attributable to the beef flavoring....

[PSam]

lol

[MiddletonMark]

I would have never thought my Acropora was saying `Beef, it's whats for dinner'

Ok, so this is either serious fate, or I'm in the wrong place! I recently acquired an A. Chesterfieldensis from a local guy. He had an Alkalinity issue from the two part he was dosing, and it measured 15dKH by the time he saw the corals have an effect. So here is the coral the morning after I got it:



And he had mentioned that sometimes "strings" would come out. I am hoping it is the subject of this thread, but here is a picture of the "strings" that I am hoping are mesenterial filaments:



Please excuse the non-focus, I'm still trying to deal with an older camera. It has auto focus and manual focus, but the manual is in larger increments than I'd like, and so I have to move the camera to get it focused, and now you are trying to focus using a 2" LCD. Grrr.

If I'm right, let me know, and thanks. If I'm wrong, eh, heck, I've got thick enough skin.

[Canarygirl]

That looks just like what I saw on my tenius after the frogspawn episode. It's also just like what I've seen in photos. so I think you nailed it.

Awesome, thanks!

some of my corals do it often and some never do. i have a couple of millepora that do it any time i even move a rock or stir the sand bed - my take feeding. i have noticed it the most when feeding the fish or home made coral food with amino acids.

[LockeOak]

I've never noticed it in montipora or acropora, but I have seen A. millepora do it when they decide that some montipora needs to die

[PSam]

Here's one of the acro in question... blurry, but you can make it out a bit:

One more for feeding -

After i get done feeding DT's oyster eggs, frozen rotifers, cyclopezze and DT's phyto, many of my acros send out their Mesenterial filaments, and if you look close enough you can watch the particles get trapped and injested.

[Marko9]

One more fore feeding. I have a kiembensis that loves to show off and spread its wings.

[checkinhawk]

im vote for feeding as well,i see alot of my corals do that when i feed rods food.my efflos seems to string up within minutes of the rods food hitting the tank.

[Canarygirl]

My corals have never displayed filaments as a reaction to feeding...it's interesting that other people's have and mine haven't. I feed Rod's Food also.
