How many tridacnid keepers here?

[BCReefer]

I have a Gold maxima about 2” now. I have had it for about a month and it has already grown. Have not target feed except for 1 time and I think I scared the poor thing. It seems to be happy but I am curious to see what others think about target feeding.

I do hear that they are big time calcium suckers? I only have a small one and I use a Kalk drip so I haven’t had a problem yet.

Question for the other keepers. If you have more than 1 in a tank, how far apart should they be? What if they are both the same colour?
