Gigas Grow Out Thread

[DeniseAndy]

Mine is going nicely. Lights out tho. Try to get pic tomorrow. Likes to lay tilted wrong angle.
I have not seen them, but have not really looked either.

Mine too is good. Contact ora and see if the still have then. You can't buy direct but they can find you a retail shop.

ORA is out right now. I got an order from Aqua SD, a couple of Crocea’s and asked about the Gigas. I wanted one a little larger then the 2 to 3 inch that they originally had as it was going into a populated 300 gallon and didn’t want to lose it. They reached out to ORA and were told that they are out of Gigas right now. I’m guessing that means out of a salable size. So still looking for maybe someone that bought from the original group that’s needs to part with theirs for whatever reason.

I have wondered if the gigas run from ORA was a one time thing myself as I never saw any that seemed to vary in age from the original import batch. With how big they get perhaps it makes sense for them to do a batch every several years vs continual production.

While perusing seasonal charts for Brisbane, Aus to approximate conditions near gigas clams and latz clowns, I came across this interesting PDF on gigas and derasa research conducted on Lizard Island.

No, I was told there were more to come.

No, I was told there were more to come.

That would possibly align then with only having batches every couple years vs continual production depending on when we see this next group hit the states for sale.

The picture is from about 3 weeks ago. The Gigas is about 11 inches. I am glad it is not growing crazy fast.

What kind of lighting on your gigas? I have one Kessil

Hamilton 400watt 10k MHs and T5 HO. I had it under Ecotech G4 Pros the first year.

I recently spoke with someone in the know specifically about gigas availability, I was told that the majority of aquacultured gigas are being sent to restock the reefs that have been harvested for food. There are a few being released to ORA and the like but that they are very limited in numbers right now and very expensive. Hopefully they will be more available in the near future. The main thing I got out of this is that they are still be grown, just not specifically for the hobby.

Are those a blue squamosa hybrid of some sort both next to and below the gigas? They are beautiful.

It’s almost three years since the ORA supply were available. I’m glad mine isn’t growing crazy fast. The shell is maybe 13 to 14” long”

Thanks. Those are Mimosas. They are beautiful. The big one is probably around 10 inches now and the smaller one about 8 inches.

At what point should i worry about the mantle looking pinched? Noticed this yesterday. Busy week, may have been longer. Last night when he closed up it looked pretty normal. My skimmer failed a few days ago and i just found it last night.

 

[DeniseAndy]

Keep a look out. May just be bothered by something.

 

[hart24601]

I have not seen a true case of pinched mantle in many years now fwiw. However I have had many clams that mantles do pinch from hydroids or if chemistry gets off, but have always resolved themselves. At this point in the clam hobby I think many people jump to pinched mantle diagnosis and FW dip and do more harm than good stressing the clams when it’s other issues. My experience the past 5-10 years at least.

That is a real stunner!

I lowered my salinity and mine started to look better. Then my skimmer quit and orp dropped off to 350 and now he is not fully open. Skimmer is up, did some water changes. Just trying to do the minimum until the new tank gets built.
