WHAT IS THE FASTEST GROWING FISH?

  • We are currently upgrading MFK. thanks! -neo
From what I have had

Fastest - koi, when I had it it went from 3" to literally 12" in 6-8 months. Thing was a dam vacuum. My butterly koi is in second place, over took my 7yo comet in size in 1 year.

Slowest- bala sharks and my 2 pangasius catfish. One of the cats is 5" and the other is about 8" and both are a few years old........
 
Fastest growing fish I've kept: RB Pacu; grew 2-3" per month until about 8-10" long.

Slowest growing fish I've kept:Clown loaches; hardly grew at all over a span of two years, then died of ich. Both were about 2.5-3" long at the time of death.
 
For me, I would say the fastest growers would have to be my 3 Raphael Cats.

Slowest would definitely be my Rubberlip Pleco.
