WHAT IS THE FASTEST GROWING FISH?

  • We are currently upgrading MFK. thanks! -neo
From personal experience

Oscars are sprouty little weeds and, if powerfed, can grow almost two inches in a month when they are between 2" and 8".

Platies are among the fastest-growing livebearers I've bred.

The senegal bichir was growing far faster than the gold dust even before I moved them to different tanks.

My tadpole madtom catfish reached adult size in about four months. Grew from 1" up to almost five inches in that time, I guess that's what happens to naturally short-lived coldwater fish raised in tropical tanks. He did make it to over three years old, so his lifespan apparently wasn't shortened much by the early growth spurt.

I'm on my second Adonis now and they have got to be among the fastest-growing loricariids.

For slow growth nothing takes the cake like raphael catfish. Some individuals prove to be rapid growers but most just chug along like they have decades to go...oh, wait, they do.



One thing I'd like to ask in this thread is how quickly killifish and other annual fish reach adult size. If a fish reaches only an inch long at adult size but gets there in two months, that's an amazing rate of growth!
 
Fastest growing fish are the ones you now have in a tank you were supposed to upgrade 6 months ago. Right before those bills came in.
Slowest are the delicate rare and valuable ones you want to move from basement growout tanks to the main Monster tank but have to be 2 inches larger or they will be food.
Just my experience.

Oscars are the fastest I think. FH's grow pretty faqst too. I think the slowest is loached, green terrors and jack dempsey's.

gt's and jd's aren't anywhere near close to being in the same league as loaches

my gt went from 3" when i bought him to 6" when he was killed by my oscar in exactly 4 months and 1 day

jd's grow around the same rate
 
My experience:
Fastest: Oscars (hell fast, i was already buy on last month he eat too many on next month like "2 extra)
Slowest: Human between 21-49 and 49 go back small:WHOA:, Clown Loach (my dream to 30cm, still now 7-10cm)

I understand Michael. the ones you want to grow quickly will not. Like my electric blue JD. I need him to grow faster or else I am going to have to set up a tank so my oscar doesn't out grow him and make him food. got the oscar months after my EBJD reached almost 2" and it seems he has stopped and the oscar grew over an inch on him.
