How do clams die? mine looks ok but doesn't respond as all

[Cobalt]

its mantel is up, a bit up but i thought that was because of a new stream pump i added lifting one side slightly. but it isn't responding to light at all. it is if it has rigamortis...

ok, he appears to be alive, but very non-response to stimulus.

will test water and post parameters tonight

recently i added a korrilia 2 that stirred up the sand a bit, and my algae blenny died from starvation. he was removed from the tank promptly. i also recently began dosing kent tech M for magnesium, two caps a day for the last 4 days. I dosed calcium too until recently i just addded a kalkwasser reactor hooks to a dosing pump for topoff. i have a jbj 28g nano cube so i get very little evap so very little kalk is dosed, and it is on a timer so it doses at 2am every day.

I also recently had a diatom bloom for several days that i got rid of by reducing lights to 3 hours and adding kent phosphate remover for 2 days. on 3rd day it was gone and pulled phosphate remover and restored 8 hour photo period. running carbon right now to try to help conditions for clam, will do a 20% water change tonight.

salinity is 1.024

150W HQI

ca is 400
alk is 9.0
phosphate is 0
mag was 800 prior to dosing

no fish
2 cleaner shrimp
2 peppermint shrimp
1 emerald crab
1 porcalin crab
1 flame scallop
1 haloween hermit
1 feather duster
various snals and hermits
many sps

looks like hes being stung by a majano or aiptasia on the side, look at the little thing right under the mantle

looks like it has a aptaisia anemonie on it, if so scrub the aptaisia off with a toothbrush and get rid of it. Its hard to say from the pic but it may have pinched mantle too. get rid of the anemonie first and see how it looks in a day or two.

you all are right, it does. its been there for two weeks and didn't seem to bother the clam so i didn't want to do more harm tying to remove it. maybe that is why the clam has raised its mantel now all the sudden, tired of being irritated by it. well it is gone now and I will monitor it.

i'm concerned about the pinched mantel comment as well. if he doesn't get better in 72 hours i iwll fresh water dip him... thanks guys

 

[skinz78]

I bet the anemonie is the whole problem. But if it still looks bad in 72 hrs just post another pic and we'll go from there.

it doesnt look like pinched mantle. what lighting do you have? i agree to get rid of the anemone, but to me it looks like flow is causing the mantle to look like that
