Clams: pinched mantal
 

where does PM desease come from and what are the main ID's of it?

ive had one crocea and one derasa that ive had for 8 months die with in the past two weeks and no changes to water params have happened and no new clams were added, the only thing that happened is that it got hot last week and the temp got up to 85.6. My sps also did not love that they all browned out but my montis. So would the temp have been responsible for causing too much stress???? I also have one crocea that ive had for a year and a half now that was not affected.

no idea of cause but might find something if you search in this forum http://www.clamsdirect.com/forum/index.php

causes are unknown exactly but clamdirect is a great place to do some research on treatments. Good ol' FW dip can take care of it.

I third the recommendation to visit clamsdirect.com.

Most often I hear of clams spawning when it gets to hot, but never pinched mantle.

How about some photos?
