setting up a small tank for one or two dwarf puffers. i know to set up two territories and to break up the line of sight. know to have plenty of plants and caves for them to hide in. what i'm wondering about is are live plants necessary of will the plastic/silk variety be okay? i ask becasue the tank is small and i'm worried about having enough light for the plants and about algae (its too small of a tank to have two dp's AND some sort of algae eater.......... unless someone knows something small that puffers would leave alone..................) any advice would be greatly appreciated!
