will clams change color?


New member
Hey GUys,
does anyone know if clams change color like corals do under more intense and higher Kelving scale lighting?
One tridacna of mine changed last week from a turqoise blue colour to brown, It looks very healthy. I had it for about one year and I don't know why it happened.
when was the last time you changed your bulbs, bronw is a color that will absorb more light so if yoru bulbs have decreased in intensity over time then that will do it, also the higher the K scale i am sure that it will turn back to blue.
You got it, a few weeks ago I moved the hqi 20 cm higher and reduced the light duration from 10 to 9 hours.( I was tryng to reduce the algae).

Thank you, my concern is gone,This forums are great!
