I bought an aquacultured one about 2 months ago. It has grown 1/2" of shell all around since. It is hardy and a quick grower.

purchased one 11/2 inch about 4 months ago. placed it into my reef, it got hammered by my regal angel and clown trigger really badly. lost heaps of shell and mantle tissue.
sold trigger to a better place and my regal stop picking on it the next day. guess he just copied what bully number 1 did. since then it has fully recovered and doubled almost in size.

Here's mine:





Those are old pictures. It's a bit bigger now - I would guess-timate about 16-18 inches across. I'm actually thinking about donating it to my local aquarium. I would think there aren't too many local reefers that have a system large enough for it, unless...moonpod?

Damn! That's not a clam, that's a wavemaker! haha Nice!
Does he blow all the corals off the rocks every time he blows?

I was at Tropicorium a couple days ago and bought 2 croceas.
They had gigas over there that were HUGE. I was amazed, and nothing usually amazes me. To answer someone's question, yes they can grow huge in literally months.

Here's a picture of mine. Had it for 3 or 4 years. It grew really fast at first, but has slowed down a bit the last year or so. That is a good thing, because if it had kept doubling in size every three month, it would have already outgrown my tank. I hope to be able to keep it for a few more years.

goodness those things are HUGE...

here is my first and only gigas.

it doubled its size in just over two months. THEN i decided to get a pygmy angel...it didnt touch any coral except clams...it loved clams. it irritated and eventually killed ALL my clams. i couldnt get the bugger angel out. i will get another gigas and put him in my zoo/ricordea tank whe another juvenile becomes available!



here is my 10 inch maxima it killed. rip!

What coral is growing off the shell? Looks like pocillopora.
Does it wipe out the tank when it jets?

Give it a flash of blue light every 30 seconds and you'll have a wavemaker.
