4 arowana in 55 gallon tank, lifespan?

  • We are currently upgrading MFK. thanks! -neo
Yeah def not a male though
 
^ 10-12" isn't big? That's not a small fish and in a standard 55 it would have trouble turning around.

A 55gal is perfect for a JD. A 10-12" is pretty max sizes for a JD and it is not that common size. Electric Blue JD do not get large as the normal JD.
 
If they have enough room they can grow that size

yea It is rare that they get that big. They are also thiner than Oscars and other"big boys". I new something was fishy about that. i goggled other threads on MFK with the same question. People said that a JD could live in a 50 gallon tank.If you happen to get a 12 incher it will need a 70 gallon tank. but chances are they will not get that big.

Lot of people kept JD in 50-55gals most sources say JD often reach 8 inches long. I never heard about 12" JD through very few JD has hit 10". Als JD is thinner than Midas/Red Devils. A few extra inches won't hurt JD in 55gal.
 
Would suggest him getting any kind of fish, appearently this A-hole has no idea how to care for anything.
