I know that certain clams will of course require slightly different lighting and care than a clam that is the exact same species. But that big of a variation would probablybe a sick clam, or other factors besided lighting killing the clam.(params, bio load, placement.)
That's the thing though, no. I breed the things too. I have for over 7 years and have been studying them for nearly 15 years. You could have two perfectly healthy croceas, from the same parents, that are the same size and the same color - one of them may survive at 150 watts while the other receives no where near the light that it needs. If you really want be to get into the ZTS (Zooxanthellae Tubular System) research of a clam, I could probably talk about part of it - but not for long. It's like plants and their vein systems sort of. While the clams may both be perfectly healthy, one MIGHT have a slightly larger Zooxanthellae Tubular System then the other. Meaning it might need more light to feed the Zooxanthellae inside the system regardless of how fast the Zooxanthellae can re-populate.
I would have to say that Squamosas are my favorite clams of all, these things do NOT have brains, but it seems like Squamosas might even be slightly more aggressive then the other clams as well. I have had two in my personal very special tank, that I have had for 3 years. Both of them went from about 1.3 inches to around 4-5 inches in that time span. They have been through several of water mishaps and still been fine. I just love those clams and at least I, MYSELF, have always had good luck with them.
Edit: Look at it this way. You know how some fish are rather difficult to keep, croceas are the same way. As are maximas, but not even in the same ball park as croceas as far as I know. If I were to buy a Crocea and put it in my tank, I might end up transfering it to 10 different tanks before I find a place it is happy, and even then it may still not be as hardy. Clams like Derasas, would most likely survive in a can of sprite, HAHA, just kidding - but they are REALLY hardy. Croceas are pretty much the complete opposite from what I have seen. My opinion may change as time goes on, but who knows.
