okay so im getting a turtle sometime this weekend because my cousin doesn't want his anymore so he is giving me the filter, the water heater (idk if i need that), the tank and the turtle the things i need are the dock and decor.
He has been housed ina 20 gal long adn he is about 5 inches long i know he need a bigger tank but im tight in budget so if you tell me i need a bigger tank asap then i will never return here

so he had rocks stacked up in one of the corners of the tank but i am going to make a dock in a 20 long that i had leftover from one of my lizards i bleached it out i also had some plaxiglass so i will put it near the top for an above water basking spot im not sure for the ramp though so i will need some ideas on that.
so if you have any help that would be very helpful
Sincerely,
Noahboa1
