crocea ok with maroons?

[timrandlerv10]

i've read that many crocea seem to need iodine supplementation, and that you should avoid crabs and aggressive fish...does my female gsm qualify as aggressive? i know they are all different, but do are they considered aggressive in general?

i cant get my nitrates below 10...does that rule out a crocea?

they process ammonia and nitrites, but mine are always 0...will photosynthetic support be enouhg?

is 175w of mh strong enough to put them 20" down?

when we upgrade, the 75 will get three 175's...is that sufficient?

in both cases, i would like the clam to be on the sand.

any interaction between clams and euphylia?

as always, thanks thanks thanks!!!

The crocea is one of the most demanding of stronger lighting. With 175 I would think you would need to do midway up in order to provide enough light. I have one midway up a 90 gallon under 250w halides. But as with all things in this hobby what works for one doesn't mean it will work for another. I would think with 175 you would want it up higher in the rock work though and not on the sand. As for the maroon as long as it doesn't decide to host with the clam it should be fine. I have some fairly aggresive fish in mine and they don't mess with the clam. As for nitrates there is some study that say clams like a little nitrates in the water, and like water a little dirty. I will say that when I slammed my nitrates using vodka my crocea lost a little color. I have no problems with my LPS but they are 10 inches apart or so. SPS is touching both my crocea and my derasa and there is no reaction. Again this is only speaking from my experience, with my two clams. I know folks who have had clams grow under Power Compacts as a matter of fact I spoke with one today about that fact. He stated he was sure it grew well because he balanced the light issue by feeding the clam. But everyone here will probably give you a different answer, as I have learned there is no absolute in reef keeping no matter how many books they write. I guess best thing is try it but be willing to give the animal away to someone better suited should it not work. I know that I have spent a few hundred buying and giving away when things don't work out (mostly fish that sometimes work and sometimes dont). Just don't wait if it starts looking like its declining ask for someone to take it. But again I think you will be fine just put it on a small flat rock or another half clamshell so it can attach.

Here's a short acticle on Tridacna husbandry. In it, the author talks about their light requirements and lists certain fish and snails as bad tankmates.

My two T. crocea live at the bottom of my tank under 250W MH lamps.

HTH,
