Question about 10g stocking....

[NinjaNomad196]

Ok... I have had my tank ready and now I added fish yesterday evening. My old platy (Gunther) and a turquoise guppy, dalmation molly, and 4 green cory catfish. Thinking of adding another guppy or ADF? Could I? Or even both? It's 10 gallons and has a Grreat Choice 10-20 gallon internal filter... so yeah. The water is getting murky,also (not even 24 hours after getting fish!) So do you think maybe that happened because I didn't wash the filter cartridge before use (only washed tank and plants and gravel.) So umm, help?

Oh yea

Btw the fishes names:
-Platy: Gunther
-Guppy: Sinjin
-Molly: Leonard
-Cory Cats: Larry, Curly, Mo, and Squirt (he's smaller, like half the size)

Here's the tank (before I added fish...) and yes, it looks dirty, but it was VERY bright and clear and like absolutely clear. Just my camera stinks (3DS)
