SPS Targeted Feeding Macro Video Experiment

Some of you might have noticed my sudden macro mania with the iPhone videos and pics lol but i thought since i was filming acro polyps catching and consuming different foods it would be a good excuse to see how polyps react to different food types that i've been adding specifically for the SPS.
I target fed a green acro mysis pulp, cyclop-eeze freeze dried and reef roids so far and witnessed the following.

Mysis pulped into small pieces is readily caught and consumed by the polyps, even large or whole mysis are caught and held for a minute or two until the polyp releases them being unable to fit such large prey in it's mouth i assume. They don't seem to close on a food item and remain closed unless the entire particle will fit inside the closed polyps.

Cyclop-Eeze freeze dried powder soaked in water was caught numerous times by the polyps but released withing 5-10 seconds every time with no attempts to close on the food item even when in a perfect place on the inside surface of the polyp to close and consume the food.

Reef Roids powder was totally ignored by the polyps, i watched many fine particles literally bounce off the polyps with zero reaction at all.

I've set up two acro frags close to the glass in the sump for macro videoing and i'm going to video the frags being target fed these foods again with the pumps off this time and they'll basically be covered with a cloud of the foods to film the individual polyps reaction clearly. I'm beginning to think that these SPS powder foods are not being consumed by the SPS at all but rather turbo charging the micro life which in turn populate the water with microscopic juvenile life the SPS polyps are consuming. No idea really but if the acros don't eat the food i cover them in i think that's pretty conclusive proof that they don't benefit the SPS directly through actual particle capture and digestion.

These are the two test subjects who remained after all the other frags took a big step back........

The macro videos will be this close so any individual polyp reaction will be recorded easily.

Hopefully some of you find my 'speriments' of some interest as there's only so much you can learn from :reading: Sometimes you just gotts get down and dirty with your acros to get to the truth.........:p
 
Not sure what i can get in Aus, i can get frozen rotifers from the LFS i think but not sure what else they have i can try. I know we have nothing like the range you guys have access to but i just asked the frags and they're game to try anything in the name of reef science.......:)
 
Subscribed! I can't wait to see the benefits, if any, to each of these foods. I have been doing oyster feats with reef chili and chili. The oyster feast seems to bring the polyps out more
 
Tonight i decided to try the Cyclop-Eeze freeze dried powder. I don't have access to the frozen product to test.

Blurb from the CYCLOP-EEZE site:

FREEZE-DRIED (LYOPHILIIZED)
CYCLOP-EEZE®
Freeze-Dried CYCLOP-EEZE® are produced from the Deep-Frozen product. The process involves the removal of up to 80% moisture under high vacuum and low temperature. Although freeze-drying is an expensive procedure it assures that important, labile, bio-molecules such as Astaxanthene and Highly Un-saturated Fatty Acids are not degraded.

The Freeze-Dried CYCLOP-EEZE® appear as a brilliant red-orange free flowing powder. The product contains no more than 5% residual moisture and is packaged in vacuum cans or bags.

Freeze-Dried CYCLOP-EEZE® may be used directly as a larval food in aquaculture or as a feed additive
in grow out and maturation diets,
as well as in the aquarium industry. For details of usage see the applications section.


When i test fed the Cyclop-Eeze a few days ago i didn't bother dissolving it as usual but simply dumped a big pinch of it in the sump with the pumps running. I normally dissolve it in water by rubbing a pinch of the powder between my fingers under water so it becomes a fine smoky mist. For this test i rubbed and dissolved the powder in a cup of tank water prior to feeding and turned off all pumps so the food could remain in the vicinity of the polyps rather than being swiftly blown away by water current.
I laid the blue milli frag on it's side so i could have many more polyps in focus with the very limited focal range i have using the iPhone. I lit the frag tank with just cool white LED's when filming and the colors are very accurate.

It's very clear from the video that Cyclop-Eeze powder when dissolved into very fine mist like particles in water gets the Acro Yummy seal of approval. :thumbsup:
I feel the powder at the size it is straight from the can is larger than ideal for SPS polyps and benefits from particle size reduction in water prior to feeding.



After i turned the pumps back on i noticed that the Cyclop-Eeze also gets the Acro Crab Yummy seal of approval :D I believe it's a Trapezia septata living in piece of blue polyped acro, i normally see this species of commensal crab living in seri's and stylos.




Tomorrow i'll feed the same acro Reef-Roids under the same tank conditions and we'll see if the results change as they did with the Cyclop-Eeze freeze dried. I'll repeat the pulverized frozen mysis test after the roids but i already know that food is readily accepted and consumed by acro polyps when reduced to the correct particle size. :)
 
Cool videos.....I believe Sps are opportunistic feeders and will eat anything they can fit in their mouths. The question is how much is actually being used up, stored or just purged later.

I've always gone by the simple observation the larger the polyp mouth the more they rely on actual food consumption. Looking at an acro and the actual amount of meat/skin they have it's hard to believe they need much.

There's always that fine line between feeding corals for the good and polluting the tank.
 
I agree with the points you raised Ed, at a hobbyist level this is about as close as i can get to investigating what SPS polyps will actually capture and consume. I don't want any reefers running out polluting their tanks with these foods, i'm just trying to show some simple tests with different foods i've been using in my tank and i have very strict control of my water quality at all times.
It is a very fine line between managing a large amount of food fed daily and the resultant excess nutrients but i firmly believe it is those who sail close to the wind in this regard who experience a saturation in their coral pigments not seen in more starved environments.
I'll try feeding the acros detritus and see if they grab the particles. I've been feeding my tanks with the skimmate paste collected from the skimmer neck for years as the heavy coral feeding results in a lot of food deposited in the skimmer in varying states of decomposition in a very fine particle size and i already know the polyps close on these particles. You may be right in that the polyps might be capturing anything that touches them and later spitting out what they later find unpalatable, i've only watched the acros for about 10 mins after feeding so perhaps i'm missing food rejection - there's only so long i can lay on my stomach on the floor to film this stuff :p

Video stills from another acro fed Cylop-Eeze about 1 min 45 secs from first to last pic, same result as the previous acro in regards to polyps capturing and closing on the food particles.

It's all good..........I'm enjoying your photos and pics. I had a few photos of one of my acros catching fish food and it did take it in.

More commonly I see the filaments like your second pic above where they're capturing the finer particles.
 
Hello Big
Outstanding results and I am pleased to say that your videos bring up some great points .Its funny because i target feed my sps tonight with oyster-feast and a pinch of coral v power and they seemed to be very happy after feeding. I am also going to video it with my Iphone 5 and share here for you to see as well this Sunday.
thanks again for all your dedicated work and willingness to share with others.

target feeding is the way to go and the smaller the particles the better they like it. Now if you make a little of this and feed it let me know been dieing to try it......and it needs a little HGH lol

Thanks guys, as long as a few of you are interested i'll keep feeding the acros all manner of things lol.

Hey Michael, that would be great if you can share a feeding video here, anyone who has a good video or pic of SPS feeding should feel free to join in as the more the merrier as far as i'm concerned. :)
Thanks for sharing that recipe here mate, i'm fairly certain that as long as all that is blended into a paste like consistency the corals will chow down. I need to get one of those kitchen whizzer things to blend my coral foods with so i can give your recipe a try.


Tonight's menu featured Reef-Roids fed under the same pumps off conditions i will use for all the tests.

From Polyp Lab:

Reef-roids™

Although originally engineered for feeding the Goniopora genus, this product has been very well received in the hobby as an excellent food source for all filter feeding corals.

The particle size of Reef-roids is around 150-200 microns. This is an ideal size for Goniopora and other filter feeding corals to feed on. When using Reefroids, you will notice excellent polyp extension on all filter feeding corals. Zoanthids, Mushrooms and Ricordia will demonstrate a distinct feeding response. And with continued use, your filter feeding corals will experience faster growth and better colors.

Reef-roids mixes remarkably well into water and does not float to the surface like most dry coral foods. This ensures a long duration in your water column to minimize food waste.

Ingredients:
Unlike many other "coral foods" on the market, Reef-roids is NOT made with processed fish meals or other ingredients that can rapidly degrade water quality. Reef-roids is a mixture of naturally occurring marine planktons including a specific species of zooplankton that is unique to our product.

Guaranteed Analysis:
Crude Protein 60% min, Crude Lipid 20% min, Ash 6% max, Crude Fiber 8% max, Moisture 6% max, Astaxanthin 150-200 ppm.


I want you to watch the video in HD and you will see something way cooler than the previous food video. After the initial contact with the Reef-Roids the polyps actually splayed open further as if to maximize the particle collection area prior to closing very hungrily on the food. This is the first time i've seen polyps stretch open like this prior to closing on any foods, thought it was very interesting behavior. I think i have to give Reef-Roids the Acro Bloody Yummy seal of approval.

The acro actually had a co-star in this video, let's call him Jerry the pod. He gets a little excited when i drown him in roids lol........ Jerry is currently on his back on the tank bottom and doesn't move except for the occasional burp..............:rolleyes: I should point out i did the test 3 times and it wasn't Jerry making the polyps close, the same reaction occurred without Jerry going nutso.......

Awesome!

But....

I think you need to send in some Allied troops to rid the tank of Jerry's and film again!
 
On watching the video again i have to agree ormet, i think Jerry has contaminated my 'speriment' so i'll redo it without his molestations lol. I might do the mysis pulp as well and then try some of the fish pellets powdered - lots to do.........
I really need to set up a very gentle side current so the food can hit them side on which is more natural along with water movement bringing the food to them. At the moment i'm dumping it on them from above with no water to stimulate whatever might require stimulating........that sounds a bit weird.
 
pappone is great, been using it for years. You'll notice awesome results using it and/or the Blu Coral Method. If you'll wait until an hour or so after lights out you'll see the true feeding response at a maximum.
