Which one should i follow...?

Question

I've heard that for every inch of fish in your tank, you add 1 gallon. but than i heard a starting fish you add 20 gallons, and 10 gallons for every added fish. Which one is correct, or is there one i dont know about.

Answer 1

It depends on the type of fish you get, like neon tetras.....you would not need a 40 gallon tank for 3, but you would need a 40 gallon tank for 3 goldfish it depends on the species. Just research the species b4 getting the fish. Like 1 oscar needs at least 55 gallons, but 2 needs at least 100 gallon, cuz they get big. Teras, you can have 10 in a 10 gallon tank, they get about 2 inches. The one inch per gallon rule is only to help beginners NOT OVER stock their tanks, once you are more expexperiencedu can throw that rule the trash!

Answer 2

The emergency rule is one INCH of fish per gallon, but then you also need to research the specific type of fish you have or are buying, because some need a lot of space.  There is no one decisive rule.

Answer 3

for every inch add a gallon.

Answer 4

i would go by about 3 gallons per fish. really depends on what kind of fish you want.  i have a 50 gallon but i only have about 10 fish in there and don't plan on getting any more.
