Dwarfs are very shy and nocturnal creatures. They honestly aren't very much fun. I had one for 4 months and I saw it actually exploring the tank maybe 6 times for more than 20 minutes. The funnest part was watching it take down Fiddler Crabs as large or larger than itself. Other than that, it would occasionally hang out on the wall of its critter keeper, watching the fish in my tank swim around it, or hang out on top of its shell, retreating inside if it knew I was around.
