Quick 10 gal freshwater aquarium questions.?

you JUST set up your 10 gallon tank with that many fish? I ume your tank is not cycled? You will have a huge task to keep your fish from all dying. Not only that, but you have way too small of a tank for that many fish, especially when they get to be adult size. See if you can return all but 1 or 2 of the fish you have, keep the tetras if possible, and cycle the tank with those. Monitor the ammonia, nitrite and nitrate levels until you have NO ammonia and NO nitrite levels at all in your tank. At that point, you can start to add more fish, but do NOT add more than 10 inches of fish, as their MAXIMUM ADULT LENGTH will be. You cannot add 10 fish that are now one inch each but will grow to be 4 inches, or even 1 foot long each. As you have it set up now, you will have dead fish, if not this week, almost certainly this month. PLEASE find out more about the nitrogen cycle of fish aquariums, and PLEASE learn something about how not to overstock your tank.
