Dersa clams are also easier to keep but do get big
Here is a squamosa and maxima

So which ones would you guys consider the most hardiest? And which ones are the most difficult? Doing a little research and most people say to find one at least 3 inches in size for better survival.
Sorry to be the party pooper on clams... but the ugliest clams are the only ones tank safe... check this out from one of the expert on clams. It should clarify why they don't last. Personally, i don't think clams should be offered in the aquarium hobby. They are amazing but unfortunately MOST will only last 3-4 years at best in a tank, if that.

I respectfully disagree. There are far too many instances of mortality rates of captive clams which are open to predation through their bisle gape or other unknown and less understood pinches mantle. Gigas can/have outgrown tanks so they too are not the best choice. Unfortunately clams are not easily harvested in a captive environment and rarely multiply and unfortunately waste away.
Nope and hell no..
Pinched mantel disease is well understood and cures properly done do help..
And yes gigas grow and get big over time so what I was just saying that clams do and can last a life time to your comment that they only do well a couple of years ..
So if you don't like them don't get one, just get you facts straight first..
I absolutely LOVE clams, that's why I wont keep them in a tank anymore. My comment on Gigas is that they outgrow tanks too quickly and therefor are NOT a good choice, not unlike some reef fish that outgrow a system that are not great choices also.

Clam studies have been taking place for many years now so I listen to the experts on the subject. However, good luck with growing you clam.

I think they live longer than people keep mandarins, copperband butterflies or Moorish Idols which are 3 fish I have no problems with. I believe all clams for sale were maricultured in Tahiti.
The "rocks" in this lower picture are clams. They are all over the place there and grow like weeds. In some places it is hard to walk because of the clams which were living right on the sand in a few feet of water. That means they need a lot of light.
I have been keeping clams for about 30 years and although I never kept one over 10 years it wasn't the clams fault. I always lost them from an accident. They are a very easy, no maintenance animal and are not taken wild from the sea. They are grown just for the aquarium hobby.
