Help Derasa shut tight

[REEFGIRL1]

I noticed that my 6" derasa (I have had the clam for almost two years)has not been opening at all in the past couple of days so I pulled it and my maxima out and sure enough found those tiny pest snails on both and scrubed them off (time to find a six line wrasse), the maxima looks better and is fully open but the derasa is still shut tight. Is this a bad sign? Do Derasa's stay shut when they die unlike crocea and maximas? The clam never showed any gaping at all.

How is the Derasa doing this morning? I just lost another one of my clams the other day. Doing fine the day before and wham dead the next day.

still shut tight

how did you get the pyramid snails after 2 years? do you have any pictures of them? and are they easy to spot on your clam?

 

[REEFGIRL1]

the snails must have come in on a coral or another clam, they are tiny and look like rice, the best way to get them off is a toothbrush

 

[hwynboy]

So should you inspect your clams reguarly? like teake them out and closely look for these things? I am not sure if I would notice one if I saw it?.?!?>

I will from now on, I've lost two clams (including the Derasa) and my maxima is not looking too good either, I may have gotten the snails off too late. I think they may have come in with a order of snails I got a couple of months ago. Right now I am looking at getting a six line wrasse and leaving my tank clam free for a while, very depressing

Just lost my DERESEA of 3 years. Always checked on the shell but never thought to check the foot. When it died suddenly I looked and there was no foot left. Snails must have eaten it and gone inside. I do have those snails as I see them on my Astreas[might explain why I'm losing those as well] but how do you clean them off the bysal gland if the clam sticks to your live rock or even a clam shell?

Can someone give me more info on these snails. I have some snails that look like rice in my tank. I thought they were baby ceriths.

Whats snail...how big...what do they look like?


There's always some kind of new pest:rolleye1:

How would one check the bottom of the calm if it is attached?

 

[john rochon]

my question exactly. Seems a tough task if attached even to an old clam shell.

IMHO a six-line or yellow wrasse should always be included in a tank with clams.

What if a person already has a mandarin in the tank? And it's only 90 gallons.

I guess you just hope that you don't get pyramid snails. A six line or yellow wrasse would eat most of the Mandarin's food supply.

Bummer.
