Moved tank clam isnt happy, anything to worry about?

[stlouisguy]

Went from a 175 where he was 34" from 250 DE on the sand bed to my new 450 where he is about 34 " from a 400 SE

Nothing around him bothering him. Moved him with no exposure to air. He has been in the tank for about 4 weeks now

My worry is his mantle just isnt coming out as it used to. I have had him for over 2 years and has always been very very healthy

Here are pics, any ideas?

Someone mentioned pinched mantle but have NO idea about that. Any help would be appreciated

Thanks

dosn't look like PM but he doesn't look to happy. he doesn't like something, maybe to much light to soon.

did you say the tank is only 8 weeks old?

its getting a lot more light then its used to. shade it for a week or so, the slowly give it more light

tank is 8 weeks old but I transfered everything from my 175. I may try to shade it for a bit and see if that helps, Ihave a slight cave I can him in for a bit.

My last light in my 6" tank was 3x250 DE and 2x150 DE MH, this tank is 4 x400 SE so light is about the same I think

that's an extra 600W and those 400's really penetrate the water. ( i think there good to like 4' )

something is stressing him, could be a combination of the move, the extra light, a new tank mate or fluctuations in your water parameters. all you can do is try to ease the stress, maybe decrease your photoperiod or find him a little shade. maybe run some carbon if your not. i keep a dersa under 10k 400w halides and he has no problems but i acclimated him to it slowly.

does he react well to shadows?

 

[stlouisguy]

Yeah he still reacts to shadow and movements. I will try shading him for a bit
