Trying to raise Dendronephthya and Scleronephthya part1

[Dr. Dendrostein]

That's my next one. But urchins and oysters I think the same way? With warm water.

Oh perhaps it is then. I thought from your post that you had to keep them in cold water to get them to spawn. I've only looked into urchins, not oysters.

 

[Dr. Dendrostein]

Where I live day temperature is 95 this time of year. I have chillers on aquarium. I let temperature in DT reach 80, then bring down with chillers end of the day to 70, all night till next day 11am(70). That should work.

My tanks are inside and tend to stay a little cooler than ambient temperature, so they stay in the low 70s. Are yours in the garage?

 

[Dr. Dendrostein]

No in home. But here soon 105-110 normal

 

[Dr. Dendrostein]

I have central a/c & evaporator cooler. Cooler in same room as DT. Big help.

Serious now, I'm throwing you a curve, like we say in America, a surprise, even for me. I'm trying to make oysters spawn(using chillers), males especially for there sperm, to feed scleronephthya. How you like them apples.

Your scleronephthya have nothing on my scleronephthya. Heehee

Looking great!!
I wonder if it would be beneficial to simulate tidal currents? I've seen some article about Scleronephthya or Dendronephthya and how they react on tidal flows. Haven't had the time to read all the articles yet. Try google scholar.
Anyway, I got the same reaction when I put in an extra pump.
So maybe it's possible to coordinate changes of flow with higher concentration of food in the water? And have periods with lower flow and food? Just some thoughts

About the oyster spawning, I like the idea. But instead of change the temperature in the whole system, maybe take out a couple of oysters and try it in a smaller tank? Just to avoid to much changes for the system. And to see if the spawning occurs.

I've had some good discussions on a Swedish forum as well about these types of NPS. Not many who has them, but still some people who are very interested.
In the Fabricius articles there's something like 95% of the uptake is phytoplankton and 5 % zooplankton. I might be a little wrong here, don't have the articles in front of me now.
Anyway, what might be the next step for us is to add a little live rotifers. Somewhere they talk about size of prey and it's up to about 300 μm. Rotifers are 100-360 μm. Not sure if they move to much or are the best prey, but they might have the right size.
But I'll try to have patience and wait until I get back to work, three weeks, before I do any changes

Happy midsummer!

Good idea(s). I think also might get urchin and make spawn. In my DT I have two eflux pumps and make one come on, one side of tank then the other. They are synchronized. Rotifers yes. What baffles me is, with all the info we have, still impossible to culture these creatures. Obviously something is missing. Also, maybe the way they have been cared for, when removed and studied, effects success in long term care. There was a time more people had these 1980's. Just to difficult to raise. When I have long tank much better success. Wait and see

I think it's time to get microscope down, see if any oyster larvae or other larvae.

 

[Dr. Dendrostein]

Ok, today received my pre-owned 7' long tank. Now going to make rimless. Need to brace top brim. Lab will be up and running by end of summer, maybe sooner.

Yipee! Can we see pics with drawn in arrows to show your plans?

When I can I'll do a floor plan layout. Thanks

 

[Dr. Dendrostein]

Sallstrom, you thought I was messing around . This is how it's done in Socal.
Slow & low. Heehee

 

[Dr. Dendrostein]

Rispa very healthy specimens. Since this video been moving eflux pumps around. They don't like it.

Yeah, all but the really red one look open and ready to eat

 

[Dr. Dendrostein]

Red ones open, some of the branches on it were cut, before I buy, makes it look like not open.

Best examples of fully open seen lately on web, on these corals in an aquarium

 

[Dr. Dendrostein]

I'm confused, the chili coral opens nights. I thinks that's the the one your thinking of. I'm thinking other red

I'm not sure which is which. I'm talking about the big red one.

 

[Dr. Dendrostein]

Heehee, I'm thinking the red with white tips. Big red one. Mainly nights. But other ones really nice

 

[Dr. Dendrostein]

Here's basic floor plan to "the lab". AKA garage
Rectangles are tables, the longest one is aquarium. There will be shelves on outer perimeter walls. Small rooms for tools and supplies.
