Answer 1

aaa cories i just love em, i have 1 peppered and getting 3 baby albinos for my 340 l tank, think you can add 2 more if they have space to swim freely :) remember they love hiding places and can help them spawn better. heres a helpfull site for cories http://www.nettaigyo.com/corydoras/encyc/index-e.html

Answer 2

3 Albino Cories plus 2 Peppered Cories equals 5 cories in the tank. I would add one more peppered cory in there to keep the bottom clean.

Answer 3

We would really need to know the surface area and the type of filtration, whether its strong enough to cope with the number of fish, however i'd be more tempted to start putting something in the upper reach's of the water.
