I once had a giant squamosa in my tank. It got so big I nearly had to break my overflow to get it out between there and the center brace. I have a smaller deresa now, but I will probably get another squamosa some day because I love the giant scutes it grows!

I love clams. Sadly, clams do not love power outages, but clams are very good at lovin’ during longer power outages, even with intermittent power generation. Lessons learned: clams spawning will and can nuke your tank if you don’t have IMMEDIATE major protein skimming & water changes. Also, protein skimming during clam spawns REQUIRES a bucket and an overflow line, because WOW, clam lovin’ gets intense.

So, um, is there a thread with the naughty clam pics?

Having had the opportunity to dive in clam fields in the wild -- those are not big clams. I'm a big fat SOB, and I have photos of my fat butt sitting inside deceased clams shells on the sea floor in less that 25' of water. I'm talking bath tub sized clam shells. They are amazing.

Of course I never came across a truly giant clam that was a spectacular colorful specimen. But their size is a beauty unto itself.

I would love to have a clam in my aquarium. I want to make the clam a centerpiece of sorts. I don’t know if it makes a difference, but filter feeders ( mostly pest ) are thriving in my tank. This makes me think a clam would be a welcome and thriving addition.

I have not had luck keeping them. I always find them being eaten by bristle worms and everyone tells me they don't attack them until they are dead - but either way I have not been able to keep one for longer than about a month.

Many years ago, used to be a guy named Barry, ran an online shop called Clams Direct. Anyone remember him? Awesome quality, healthy, beautiful clams, several varieties Squamosa, Derasa, Maxima, Gigas...

Dearly wish there was someone offering similar livestock today.

They're farming Tradacna species all around the tropics these days... FOR FOOD!

Why, oh why, are we paying a hundred bucks for an inch long ORA clam grown in the Marshalls, when the locals are getting them cheap enough to plate them up with linguine!

Oh, and yeah, I've got a 4" Squamosa. Has about doubled in size over the last year.

My Derasa, first one I had was very reactive to light and seemed to be growing, but died after a few months. So took another chance with this one. I almost doubled my ligh output. When i feed the tank it actively eats and has more than doubled it's size. It is sitting on a clam jammer. The problem is i think it was ocean grown, the shell appeared to have been heavily cleaned almost looking ground. It is the only thing added to tank in almost a year and now i have to get rid of aiptasia that showed up at base of shell and started spreading from there. Thought about a copper banded but they are not really safe. Peppermint shrimp work but not sure they will last with my flame hawkfish

The reason we pay more for ours is that the ones in the aquarium trade are more colorful and have nicer patterns.

I've a maxima and a derasa currently. I'm inclined to have more, but I want to be 100% certain about their health before buying. I'm a big fan of aquacultured clams and am thrilled that wild caught ones aren't a thing anymore.

Back in the early 2000s I had two maximas that were doing quite well over a long period. Flush with my success I sourced another one. Within days of putting the third maxima in the tank all three took a turn for the worse and I quickly lost all of them. I later learned that many on the market back then came with parasites and could rapidly wipe out a collection when placed in a tank.

I've eaten Tridacna while traveling in Asia. It tastes OK, but nothing special. I much prefer mantis shrimp! :)

I'm keeping my clams under MH + T5s at a depth of 18 inches and they seem happy and growing well with that. Keeping calcium up for them and the SPS is my current struggle.

Good book and he gives par numbers that most people don’t achieve.

Maybe on Reef Central still? I might have pics somewhere on a backup hard drive, but I’m not sure. I was a little more concerned with handling it than photographing it.

They are so beautiful. As I have progressed to 6 months of Saltwater experience the invertebrates are what interest me the most about my tank. Could care less about the fish, because the fish worth owning (imho) need 200+ gallon tanks to even be happy. I def want to own a clam in the future.

All shrimp will attack your clams. Also watch out for blennies. I got a star blenny in with mine, so far it is ok but depends on fish personality. The cure for your Aptasia has to be Joe's Juice by hand.

I'm sure they were also glad that you respected their privacy.

On a serious note it's basically an organics overload in the system right? Would a coral spawning event in a tank crash it?
