Deresa foot fell off?

[laf-reef]

I just watched my deresa fall off it's rock.... when I went to check it out it appears that it's foot separated from the clam. What should I do?

 

[mrbncal]

stand it right side up up in teh sand, in my experience with derasa they were more happy to be flat on teh sand then hanging off the rock work.

 

[laf-reef]

here it is an hour later.... it stood itself up

looks like the byssal thread and not the foot.

are you running any GFO? ( Fe based phosphate remover )

or dosing anything whit Fe in it?

how long have you had him?

does his mantle always look like that??

 

[laf-reef]

no I'm not running any GFO

no dosing of Fe

I've had it for 6 months or so

mantle usually extends more than that however never extends fully IMO

 

[a4twenty]

is it usually curled over on itself like that??

how do you maintain Ca and Alk?

could you post another pic from above?

 

[laf-reef]

the tank is a 120 48x24x24 with 4x54 T5 (3 daylights + 1 actinic)

CA and Alk are maintained by a CA reactor (typically 370-400CA & 8-10dKh)

typically the mantle is not curled - it is typically over the edge by about a 1/4" all the way around

I'll try to get a shot from above

 

[laf-reef]

here's a shot from a month ago

looks like PM, i'm not talking about the extension of the mantle more the way the edge is rolled in.


mine in the very early stages

another crocea and derasa in the early stages

yours looks to be more advanced, if your not dosing iron you will have to do a FWD.

do you run carbon?

 

[laf-reef]

no carbon

I did a FWD about 3 months or so ago... to be honest I didn't see much of an improvement and I prefer not to do another one

[a4twenty]

some times multiple dips are needed to get all the protozoa. you could try running some carbon to see if that helps but if it keeps getting worse i don't think you'll have a choice.

another link to see the results

 

[laf-reef]

I'm gonna go add some carbon now.... thanks for the advice

 

[a4twenty]

no problem and good luck


do you have any other clams in the tank?

 

[laf-reef]

no other clams - this is my first and only clam
