Maxima clam’s mantle is not extending

[jennyQwQ]

Hi! So my maxima clam have not grow for a while. I think that might because of my alkalinity swing, it was 4.1 at some point. However, that is like 3 weeks ago. Since then my maxima mantle is not fully extended. It is opening really well but the caudal end of mantle just not out properly. It is hard to show it on photo hopefully u guys can see it. I just wonder what causing that. It does not look like pinched mantle disease to me cause it haven’t developed. Anybody knows anything about this?

Def not pinched… could just be new growth? I wouldn’t sweat it myself..
