I realize these aren't the best pictures in the world, but if you could take the time to let me know if they are male or female it would be greatly appreciated! Also is my tank overstocked? If not, could I add 3 cory cats? Thanks so much! Easy 10 pts!!

Answer 1

You're tank is not overstocked.  Make sure you leave grow room for the fish.  You can easily add the cory's if you have a good back pack filter.  The aqua- tech 30-60 power filter from walmart ( I suggest this because of how easy it is to find the filter cartridges.  As for the s*x goes of the fish, its really hard to tell from pictures.  Each species of fish are different to s*x.  You can look it up online.  

Answer 2

i do not think this tank is over stocked and the 1st 2 fish in the pictures it could be eggs or 1 like the black mollies, could just be made bigger thn the male to determine the s*x....1 or the other is what i think! if eggs, good luck with babies!
