i bought 8 F1 "Ae." Rivulatus and put them in a 60 gallon tank with silk plants and a few odd hiding places.. and then i proceded to feed an empty tank for a year. the food always disappeared, but the ONLY time i saw them was when i moved the decorations and plants around to clean the tank.
when i moved them to the 110 in my bedroom i got to see them more.. but not a lot more.
