Clam with pinched mantle

[tix221]

thanks Myka!

It is pinched in some areas(mostly near the bottom) and I see some white spot on the mantle( not sure if it is bleached or something else) . I thought it was stress related as I didn't take enough time to acclimated it but it doesn't go away. Today, the mantle extension is better but the pinch is still there. I am hesitant to dip it as it may stress it more but I read that you should do it when the clam is not too weak otherwise, it won't survive. Do pinched mantle just go away by itself or I have to take some actions ?

[i have crabs]

Ive done freshwater dips 2-3 times and it worked out well

I have dipped it for 20 mins. It opened a little after I put it back to the tank. Do I need to do this again a day after it is not fully cured ? How long would you wait for the second dipping?

Thanx

I would wait 5-7 days. I've never had to do a second dip though - the clam is always either cured after 1 dip (it takes a few days to look better), or it dies a couple days after the dip. For the record, I don't think it was the dip that killed the clam, I think it was just too far gone.

Parasitic snails can also cause pinched mantles.

FW dips are only good for Perkinsus Olseni which is a protozoan parasite. Similar to Ick in fish. It is also a legally re-portable disease so do be careful. ie. If you suspect P.O. you must report it to CFIA.
