Beginner Gardening: planted too many seeds too close together, 1 by 33shadows

As my first attempt at growing anything I've planted capsicum seeds in one pot and cherry tomato seeds in another. I wasn't very confident that I'd get them to grow so probably overcompensated with the number of seeds I planted. I now have a lot of healthy looking sprouts growing closely together in each pot.

I'm wondering when they will be strong enough to separate them and how much space they each need?
