2 baby Belize sliders will be arriving at my house tomorrow and i'm not prepared for them. I need help with housing and equipment. I plan to buy a 20 gallon long aquarium. Someone recommended the Penguin 200 filter by Marineland. the issue that i'm having is that with a hang on the back filter I would need to raise the water level almost till the top of the tank which wouldn't leave room for a basking platform. if anyone knows of a good quality basking platform for a 20 gallon tank that would be great. I've been surfing the web for ideas but i'm not having any luck. Some filter suggestions would be very helpful. Also I was looking into basking platform that goes on top of the tank. The only one I have seen so far is the "Turtle Topper by penn plax but i'm not a big fan of the way it looks. Lighting ideas would be helpful too. Thanks guys.
