Clams in a nano?

[Tamberav]

I mean... This light is over $250 and marketed as a reef light. Not as a 'soft coral pico tank' light.

Money spent does not mean much in this hobby

It is 16 led's, one is moonlight, one green, one red, now we are left with 13 leds.

You are left with even less if you don't run whites and blues at max. Many don't run all at max due to not liking the color, fan noise, wear and tear....

You could run your light from your 90 over your 15g cube...

Fans are to cool the tank when the temp hits 79F. They are connected to an Inkbird.

Others on the forum like @minus9 can advise better on crocea placement when you want them in the sand bed. Maybe making a cradle for the crocea to lift it off the sand will be more comfortable for it. Getting enough PAR on the sand bed may mean blasting the rocks with very high PAR, though.

Croceas want a solid surface to attach to, so they can live on the sand provided that there's enough light and they have something solid under them.
If it were me in this situation, I would pick a light for the animals I want to keep, adding several fixtures can look a little funky, but that's personal taste. I would pick a light that can replicate a nice "daylight" spectrum for at least the peak hours of the day and you can "blue" it up for the ramp up/down. I would much rather have a light that I'm only using 50% of it's power than max out a light that barely has enough power. If you want to keep a clam, especially crocea or maxima, you need a light that can provide them with everything they need. Look for a used Kessil 360x, it would light your nano and has a great spectrum. But you can also find nice powerful fixtures on Amazon, Aliexpress, etc...if you want to keep a clam, the only thing that really matters is the light, it's what drives them and provides everything they need. I would look for a slightly bigger fixture and simply reduce the power.

Also have a look at the K7 Pro over the 15. Less than a Prime and would more than cover all of your lighting needs on that 15. Would look nicer as a single LED as well.

Thanks. I just made myself a 'clam cradle' to make sure I can perch that guy as high as possible. And... It's so inexpensive, I'm going to experiment with a Hygger 30W and it run it at peak hours alongside the AI. It won't look great. But I will definitely keep an eye out for that Kessil. I've always loved the shimmer on those.

I would look into Reefi Uno for a nano. Built like a tank and lots of top quality leds and twice as many watts as the Kessil 360x with a 3yr warranty. Amazing lights IMO I have AI Prime and Hydra on my other tanks. NEVER again will I use their lights.

Just monitor the shell growth, that will tell you everything you need to know about its health.
