New update: my sister's fish died (sadface) buuut I was given it (it's ten gallons). In december I set it up with a shrimp (freshwater) and three little platies (males). They're all white with red tails and black dots. They've been doing great so far, and it's really been fun to take care of them. The pond has, for now anyway, been put on hold. I think my dad realized how much college for me is going to cost. =P
But yeah, the fish are doing really well, and they seem happy when people aren't too near the tank and when the cat isn't batting at it.
I'll see if I can get a good picture of any of them.

The best I can do in MS Paint.
