Okay so I am a little guilty of not having a big enough setup.

My Spike grew faster than I expected and grew about 2 inch in the past 6 months already. She is now 3.5 inch. I still have her in a 10 gallon

I live in a small apartment in the city, so I don't really have enough room or money atm to buy a 4o gallon setup. When I bought her I just knew I had to have her, and I bought her from a Chinese 99cent store. At the store they have about 20 hatchlings in one of those tiny plastic tanks that they give you when you win a reptile at the fair. They have no heater no basking area and not heat lamp.

I just figure that any setup I am able to provide for her is better than the hellhole she came from. And my girlfriend was in a rescuing mood and brought home a little 1.5 inch one day. So now I am really feeling like it is way overcrowded now after hearing about the 10 gallon per inch rule. I just don't know what to do. My friend is willing to give me his 20 gallon long tank. Would this be sufficient until I am able to buy and find room for an adequate setup. Thank you for any help. I am also going to be in need of a better filter than I have atm, if anyone has any suggestions.
