I have one just sitting in the garage, but its a salt water set up. 25 gallons and has everything you'd ever need to get started.
Bugs, my wife has been using one of these things for a year. She did the same thing, beta fish and some decorations. Have fun growing some plants!I just got this tank a couple of weeks ago. It is a aquaponic tank. 3 gallons. The plants absorb and use the fish waste to grow. I have a betta named P.F(Pet Fish/Plant Food) Chang.... and a few shrimp. Fit just perfect on my tying desk. Decorated it with rocks and driftwood from the river down the street. Been fun so far. It gets decent light on top so hopefully i get some greens in a little while.
