AGAIN, people that can't/won't purchase the correct/best lighting rationalizing and justifying why it's okay. Rapidcrab, with great info being handed out like that no wonder LFS get a bad rep. I have a small almost non-profit LFS that I started to just help give GOOD information. Can you live in a cave for a months or a year with little to no light, yes. Would you be healthy and happy, no. Can you keep a corcea or maxima under PC's, yes. Are they healthy and happy, NO. Would you or the clam make it to two years? five? Probably not. There is no subing for MH's ( maybe T5's, un sure still,IMO) I have 18 clams in three sifferent tanks and would never keep them under anything less than MH's.
Tmplge - Your telling me that those clams are 48"+ under PC's and doing fine? Not without natural sunlight or a tank next to it producing enough light . Or its been a few months and they are very slowly dying, or possible what type type of clam.
Natsak - That's a terrible thing to put out there. You are saying lighting doesn't matter, only clam placement. Do you work at a LFS also? The advice we give on RC should be tried and true, not "I've really lucked out and have done this" advice. There are people trying to learn so that they can keep healthy animals.
I reef so that I can enjoy the sight of healthy, happy animals, not just so I can have them. I'd never have or sell an animal where there isn't the right equipment, food, or information for long life.
The rest is garbage info, I'm sure I can keep a dersa under a 200 watt house bulb or a small fish bowl in the window, but I won't.
Racso - get all the info you can, then buy the CORRECT lighting and have happy, healthy, LONG lived clams.
Sorry, this type of thread always ticks me off and always pops up - The JUSTIFERS just won't give up, they'd have to admit they made mistakes.
