What species has the highest growth rate?

[clayt101]

How about common plecos? They grow pretty fast.

I don't know about plecs,my common plecos grow slowly maybe because it eats only algae on the glass.Pacus are fast too,bichirs are a bit slower.

What about goldfish? They grow pretty darn fast, too.

Guppy fry grow visibly in a matter of days.

my votes are for red-belly pacus or channel cats. i have had both and they grew like weeds.
