I have a 6" african aro in a tank with about 12 bichirs. The bichirs are pretty messy so I was thinking about taking out the black sand in the tank and making it barebottom. Is that a good idea? Do African aros need sand to sift through?
African Aros are okay without sand. It's not a must for African Aros. I've kept African Arowanas in barebottom and sand. They seemed perfectly fine in both base.
