So far on my setup, at most I may have 150ish in a 10 gallon.  I now have 2 sets of egg laying perc's and they hatched egg's a day apart.  I am currently running low on extra space, so I mixed the babies in the same larve tank. My larve tanks are standard 5.5 gallon tanks. I keep them half full at least through metamorphsis. Right now, I have a few hundred in this tank, with the rest of a split hatch from my 1'st pair due tomorrow early afternoon. My question is, when I put them on the system at day 30, how many should be kept in this 10 galloin tank?

HMM. First, I have to say - There is no wrong or right answer to this question.

I'd certainly think at day 30, you might still be OK with a couple hundred in the 10 gallon tank. By day 60, you may not want more than 100 in there, and by day 90, you may not want more than 50 in a 10 gallon tank. I'm just throwing that out there based on my own experiences and setups...your filtration and maintenance routines might make those numbers deviate. I've not done a LOT of high density clownfish rearing, so maybe some other folks who have might chime in too?

Mixing the 2 batches hatching a day apart is totally fine so long as they're both the same species & variant (just so you can keep things straight). Of course, from a breeding standpoint, it never hurts to keep them separate (i.e. you could learn that you have better success with one pair's offspring).

FWIW,

My future plans are to keep them apart, this way I can mix up and get some bonded pairs to sell and not have them be inbred pairs. It ust happened I was very low on fry tanks.

Do you know for sure that the parental pairs aren't siblings themselves?

I am not 100% sure. But I got my original pair about a year a go from a local guy. I got the new pair a few weeks ago from a not so local lady up north. And they were at least 2 years old.  My original pair were about 2 years old when I bought them. I think they are not siblings but have no way to be sure.
