Ok I'm gonna get a few rbp, and I just bought a 20g long aquarium, and I'm wondering if getting like a sand bottom of the aquarium would be harder to clean or be more of a hastle than just original rocks. It wouldn't be sand, but a little bigger. What does everyone think? O and don't worry about the p getting to big for the tank. When it comes to that, I'm gonna give them to my bro who has a 55g that he just bought. He has 2 rbp, the 3rd died recently for unknown reasons.
