150 gallon tank FAQ
How many fish can go in a 150 gallon tank?
It depends on the fish, not a fixed number. A good example for a 150 gallon is 5 Silver Dollar, 5 Clown Loach, 1 Blood Parrot Cichlid, 6 Drape Fin Barb, 4 Festivum, 1 Nerite Snail, which comes to about 79% of a cautious stocking limit. Small, tidy fish like tetras and rasboras let you keep more; messy fish like goldfish and plecos fill a tank much faster.
What size heater do I need for a 150 gallon tank?
A 450 to 750 watt heater. Go toward 750 W if the room runs cool. At this size, two smaller heaters at opposite ends are safer and heat more evenly than one big one.
What size filter does a 150 gallon tank need?
Look for 600 to 900 gallons per hour of flow. For messy fish or a busy tank, go up to about 1200 GPH.
What are the dimensions of a 150 gallon tank?
A standard 150 gallon is about 72" long, 18" wide and 28" tall. Brands vary slightly, so measure before buying a stand or lid.
How much does a 150 gallon tank weigh?
The water alone weighs about 1,251 lb. With glass, gravel and decor, plan on roughly 1,500 lb, so use a stand made for aquariums.
