This is our 40 gallon hexagonal tank. This tank is running an Aquaclear 300 and a Powerhead 201 on the undergravel for filtration and a 200W heater. This used to be our goldfish tank but we moved the goldfish to our 55 gallon and the 40 gallon is now a community tank. In the 40 gallon there are Gouramies (Three spot, Opaline, Sunset, Neon Blue, and Giant), Barbs (Tiger, Strawberry, Rosey, Long Fin) a Betta, and a Fiddler Crab.
Thanks for visiting!
