Help, Clam Turning White ... Too Little Light?

Recommended Posts

Rehctelf

Help ... my three month-old clam is turning white (see attached pic).  It has been slowly fading to white for a couple of weeks now.  However, its mantle has been opening wider than ever.  Could this be from too little light?  Parameters are all awesome and everything else in the tank is doing great.  JBJ 30 rimless with a single Kessil 360WE Tuna Blue for light that turns on and ramps up from 15% at 8am to 80% at 2pm and then back down to 15% at 8pm and then off.  I keep the water temp at 76 degrees and salinity at 1.023 ...

 

Should I move him from the bottom to half way up my liverock?  There is a spot for him there ...

 

Thanks in advance ;-)

Do you feed it? What are your calcium and alkalinity levels?

If you think it may be lack of lighting causing it you can either move the clam up higher or raise the lighting to 100% at peak . Good luck.

Zoaxanthelle doesn't tend to live in the parts that get less light..  either place it more direct under light, or wait to see if it is progressive, or gaining color back..  Gape is usually the biggest indicator for big problems.
