My tank. It's a 20g with 5 adf plus corys, ottos and platys. I'd say sand better than gravel, plenty of hiding places, leafy plants (they like to hide in, on or under), they eat sinking pellets, algae wafers, blood worms, brine shrimp. They like company so would recommend more than 3. They can be slow to food but I've never had this problem. Make sure tank has a lid as I've had 1 escape (even with a lid on)
