Yep.
Want to point out one thing though...
They are NOT freshwater fish!!! They are Brackish or Saltwater fish that can only live in freshwater for short periods of time (just long enough to be sold to you and die within weeks). A Specific gravity of 1.020 - 1.024 will suit this species. Grows to a foot in length. Known for making a 'croaking' sound that can be heard well away from the aquarium.
