It looks great! Keep us updated.
It looks much better!! Keep an eye on it as it looks like you had to place it in the same spot.
The progression of the disease is not PMD as I know it. I think the hypothesis that PMD is caused by Perkinsus IN THE TISSUE of the clam is wrong. If you read the article by Basti et al, they isolated Perkinsus from the tissue some of the diseased clams and some of the healthy clams. They also did not recover the Perkinsus from some of the diseased clams and other healthy clams. This really point to an incidental finding finding.How can you say for certain it is not PMD? None of us truly know unless you can take a sample from the mantles tissue. The freshwater dip obviously worked so how can you say it wasn't some form of perkinsus? Anyway, I'm just happy the clam looks much better for the OP and hope it continues to grow.
Thanks for the info my friend.The progression of the disease is not PMD as I know it. I think the hypothesis that PMD is caused by Perkinsus IN THE TISSUE of the clam is wrong.

I have two problems with their conclusions after reading trough their paper:
1. Tissue infection will not response to FWD. The basis for why FWD is effective is that it rupture and kill surface parasite due to exposure of small organism to fresh water. If the infection is in the tissue, the pathogen will not be exposed to fresh water until the clam is dead and all the cell of the clam ruptured thus exposed what is in it to fresh water. They were looking at the wrong place. Rather than looking at the surface of the clams, they looking at tissue slides for internally infected pathogen.
2. The pattern of Perkinsus isolated in clams, both healthy and diseased clams, and not isolated Perkinsus on other healthy and diseased clams points to unrelated incidental finding. They cannot conclude that Perkinsus as the likely cause of PMD. It is much more likely that Perkinsus is a unrelated finding. They have a preconceived notion that Perkinsus is the pathogen and tried to shoehorn their finding to fit what they think is the answer.
There are three possible explanations why the OP clams is doing well.
1. The clam had PMD. IMO, this is unlikely because I don't think the clam had/has PMD
2. The clam was transiently affected by a number of chemically/environment related factor. FWD did not excessively stress the clam and he recover once the factors affecting him removed.
3. The clam my be affected by a difference surface parasite/pathogen. Treatment with FWD will kill most if not all small surface infected pathogens, not just the PMD pathogen. If the pathogen is a tiny organism with exoskeleton, then it may be more resistant to FWD.
look for injury on the mantle. Something is picking/pecking him.
Are you feeding phyto? I’ve found the smaller clams seem to do well with feeding phyto, until they get larger. Also, isolating the clam in an acrylic box could help with preventing tank mates from pecking, and help with isolated feeding of phyto.
