t. crocea - mantle rot?

[MarkHenry]

Hello!

I bought a t. crocea at my LFS Wednesday this week. What I thought was white colorations in the blue mantle are now turning out to be some kind of mantle rot. Here are some photos (warning: they're rather large! the last is the smallest at 250k) for reference:

Any idea what's going on and what I might be able to do to fix it? My tank parameters are good, ammonia 0, nitrate 0, nitrite .1, PH 8.4, salinity 1.023. It's a 60g tank with MH lighting (the clam was under MH at the LFS). I spent 1.5hr slowly drip acclimating the clam and never allowed it to contact air during the transfer. I started it up in the rockwork, but it didn't like that and kept jumping to the sand bed, so I left tit there where it seems happy for now.

I'm concerned because this was apparently starting at the LFS before I brought it home and it has accelerated over the past 24hrs. The clam is still light and touch responsive. I have also noticed that some t. crocea at clamsdirect.com exhibit similar scaring/molting/etc in the mantle, so I'm not sure that this is actualy a problem or not - but I'd rather ask to be sure.

Any help would be greatly appreciated.

The clam looks fine to me. That is typical coloration for a crocea.

Hello,
I would kick your salinity up to 1.025. That might help a bit. I had the same problem with the lower salinity.

Look at D2 and F2. They are not exact but they do look similar. I do prefer the 1.025 as the salinity, however that alone would not cause anything. Also I have been in this hobby for quite a while with an emphasis on clams and have never heard the term mantle rot. Is this your description, or is that what somebody told you?
