With their desirability in mind, if you can find a good specimen these clams can be relatively easy to care for in a well-run reef aquarium. However, they do have particular lighting requirements, and are by no means bulletproof when it comes to keeping them long-term. So, this article will cover their basic biology, how to identify them, and how to best care for them in aquaria.
A few years ago when I was working on my book about giant clams, I was lucky enough to get a tour of the CV Dinar coral and giant clam aquaculture facility in Indonesia. I'm sure a lot of hobbyists have heard of the "farms" in the Pacific, but I figured I'd give you something of a virtual tour of the place and show you a bit about how things are done there. It was quite interesting to say the least.
To summarize, it is impossible to give a single number recommendation when it comes to tridacnids' lighting requirements, even for a particular species. Each clam is genetically different, and some members of a given species will need more light than others.

This article concludes our brief and incomplete look at copepods capable of potentially harming our captive animals. However, the series will continue with reports of other parasites, including nudibranchs, sea spiders and other 'creepy-crawlies'.
While you might never see a porcellanus for sale, there's always the chance you will, and hippopus is easy enough to acquire if you want one. So, keep all of this information in mind and do what it takes to keep them alive and well should you make a purchase.
Even under the best conditions, only a small percent of the eggs ejected in a spawning event will actually get fertilized, and of those that do, maybe 5% will make it through metamorphosis, or even far fewer than that.
