Iam thinking about getting one for the 150gallon piranhatank, witch one should i choose? Koralia 4, 5 or 6? I want to give them a good current to swim against.

any of the above would be fine, I actually have koralia 8 in my 180g.
how big are your piranha? as long as you have dead spots you'll be fine.

 

[Kristoffer]

ok, thanks. 9.4 inches including tailfin.

 

[jp80911]

then you can go with 6 if you want to, should be fine.
