Clam leaving residue on glass

[sk8elenex92]

Every time the clam moves toward the front of the tank pretty much touching the glass it leaves a white residue on the glass. I'll move the clam back and it will scoot it self back to the glass. I think it gets more light since a monti shades it a Bit.
The white residue is super hard to scrape off even by hand and a razor. It usually takes 5 days till it start growing again. Really weird, I'm thinking its some calcium growth on the glass from the clam sucking down so much calcium. Ha. Stupid guess but I No idea.

Love the leopard wrasse

What are those corals next to the clam?

@Tahoe61 @DSC reef
I've not see this before.

I see a cyphastrea coral on the left. The film on the glass is from the underside of the mantle. Use a blade or scraper to remove. The cyphastrea looks similar to "candyland" cyphastrea.

 

[sk8elenex92]

DSC reef is correct, the one on the left is JF candy land cyphastrea.

I use a razor blast but it's come right back and just in front of the clam. It's also really really hard to get off. Coralline algae doesn't compare.

 

[saltyfilmfolks]

My concern was stinging.

 

[sk8elenex92]

Oh. I have a bunch of coral TouchIng it. Chalice. Zoa. Monti. Haha. There is even a stupid poccilopora sps growing on its shell
It's always open and big. I've have it for little over a year. Started really small.

Didn't know they grew so fast.
This is from July 20th.

When we had our large squamosa if the underside of the mantle touched the glass it would leave the same residue.

I think I read somewhere in James article about clams immune to corals sting, I got clam that Aiptasia grow right under it mantle and the clam seem not getting any sting effect and its open wide to cover the Aiptasia like its worry for the little thing having too much sun batch and get tan....

That's quite interesting.
Hmm.

It's like a slime coat. It seemed like it was just the underside though. I was constantly trying to move him away from the glass because it was a pain to clean but he was so big. I'd move him then he'd go right back to his happy spot. Lol. The tank doesn't look right without him.

I wonder what that is. You'd think we'd notice it with any clam in most placements.

 

[DSC reef]

I'm not sure. It didn't seem to be a stress induced action. My theory is a slime type coat to make moving in and out of the shell easier. Maybe that's why the inside shell is so shiny??

I knew how you feel, when my GATF passed the tank look really odd without him and I ended up sold the tank cause I refused to raise another GATF.

Mine does the same. I'll move it and the next day it will be back to its spot. Ha. I can't imagine the tank without it now.
I got another maxima as well. Hopefully gets this big.

It's weird because the glass underneath Doesn't have that residue. It's also sitting right on the glass.

The squamosa was the highlight of tank for sure.

Yep, just the underside of the mantle leaves that residue.

Yeah, it will get big but you will need multiply by 10 years to get to catch up with Derasa size

 

[sk8elenex92]

Yea I'm very surprised how fast this deresa grew.
Guessing Maximas grow much slower.

hahaha yeah!
I got babies Derasa and Maxima same size go into my tank same day, 2 months later the Maxima show a new set of scute but size pretty much look same while the Derasa already more than half inch longer than the Maxima I sold the Derasa because I knew it will out grow my tank in a rush of time.
