Well, all Oysters i know live completely underwater, BUT they need a lot of water flow or movement.

High concentrations of oxygen are fully necessary...

They should be fine. Just make sure they're in a well oxygenate spot with strong water flow, as Rvs said above. They are filter feeders, so you may need to supplement their diet with plankton or rotifers. I imagine care would be similar to clams.

Thanks I think I put it in the right place I will see how it goes...Puffer is a little on the small size to get them ATM..I hope.

RVS. The oysters here are in tidal zones and spend at least 2 hrs of low tide above the water line which is a bit hard to simulate for me at present ( would like to make a tidal tank with a low tide area one day) ..The rock I collected was just out of the water with 3 hrs of the out going tide to go .

I'm not 100% certain those are oysters.

Yes, they are mollusks but possibly from the clam family?

Most oysters are more elongated as opposed to wide.

Either way, I would assume care to be very similar.

Snapper, for curiosity's sake, do you think you could post a close up image of the mollusk?

There in the oyster family for sure 100%, multi million dollars Austarlian seafood industry for southern rock oysters that are grown on flat bead cages in tidal zones of the NSW to Victorian and across to SA ( sydney to perth) coast and exported to many parts of the world .I like them cooked kilpatrick style (bacon black sauce on rock salt) had my fill of raw when I pick them as a teen for $2 a basket and 200 bandaids(plasters)..Im so good to you guys I translate..hehe

We have 3 farmed species http://www.sydneyfishmarket.com.au/FISHline/SpeciesInfo/Oysters/tabid/170/Default.aspx

Edit..Maybe its a cultural thing too as to what we Aussies call Oysters and clams and what you guys call them ..

Do you think the plankton coral and invert foods for tropical marine avaible on the market will do the job ?

Ive posted a few links of Australian oysters above...Very Happy

I can't answer the question directly, but I can tell you about a type of clam feeding that worked for me and one that didn't. In my previous tank I fed home made food about 5 times a day, and lots of it too. It was based on the "Borneman famous recipe" of a blended mix of seafood, frozen fishfood, and dryfood. In addition the tank was literally full of reproducing macro algae. No clams grew well. Some stayed alive though. In my current test system I feed clams continously with live phytoplankton. At least 4 species, including north atlantic oysters grow very well in this feeding regime. I have only had one die off incident with clams, and that was in the beginning of the experiment. So getting enough food is the major challenge with coldwater clams. I don't think they are dependent on high flow since they generate their own flow over the feeding organs.

From what I've been seeing, your second method of feeding seems to be the most common and successful overall.

Jon, do you think that a continuous feeding cycle is necessary? Of course, this might be the best solution since it replicates natural environments in the wild.

most of the ones we see here are more elongated and usually from deeper waters. Thanks for the links btw Very Happy

Perhaps because they are freshwater oysters - thinking Great Lakes? I've found numerous oysters in Newport Bay, clearly visible from the surface of the water, that look similar. Of course, not all species look exactly the same.

The great lakes are clams and mussels.

The Oysters I was thinking of are cultured in beds about 20 ~30 feet under water. They also appear on deep rock.

I'll have to look up the different ones to get a clearer idea... and for self education Very Happy

The only Oysters cultured here in 20-30 ft are mother of pearl oysters .
