Just got this, the lights at the lfs are high dollar and super bright. Just a couple feet from the clam. Anyway I noticed that it's starting to brown out and since I have lower lighting and can use a filter feeders I spent a little over a c note on it... Just because it can live a long time and is just a beautiful thing to have... Thinking it will color up here.. blah blah blah.. are they supposed to be brown? I will get it on rock later, right now since it is aquacultured it's attached already to a hard piece.. under the sand. Stable prams, 40k lux light a few feet above. Par is not known right now.. what kind of condition does it look like it's in? I had to remove a dratted moon snail off it. Thank You for the time.
