Motoro Growth Rate Male vs Female

[haxjester]

I was just curious if there is a noticeable difference in the growth rate of a male motoro to a female motoro? Has anyone noticed one growing faster than the other?

The reason I ask is my male has definitely put on a little size since I got him, but the female looks like she hasn't grown at all. I've had them for about 5 months now. The female was a little smaller than the male when I got them due to her being about 2 months younger. He is about 6-7" disk, and she is 4". They are both less than a year old. They both eat well, the female especially, she's a very aggressive eater, on massivore, market shrimp, tilapia, silversides, and live feeders (once in a great while). She's not skinny, she usually has a big butt from all the food she eats, and her tail is nice and thick, her behavior is normal,the tank parameters are all great, and she's not being bullied by any other fish.

Anyone have any ideas, similar experience, or is she just a slow grower?

Females. almost always outgrow Males.

You female must not be eating as much if the male is growing faster...

for instance my male and female Motoro were the same size @4-5" 3 years ago.

My female is now 15.5" and my male is 10.5"

usually a motoro is around 8-12" at 1 year of age.

My male full Motoro out grew my female Marble x Motoro by 2 inches in an 8 month period.
But he was much more aggressive when feeding.
But since I sold him she has started growing much more. She has put on 2 inches
in the last 2.5 months. Now just under 9" and will be 1 year a on Christmas day.
Now the two WC marbles I got at end of sept are growing bout 1/2" a month,
almost. The have went from 5" to 6.5 - 7 inches.

OK, maybe I have a freak female motoro, I got her last February at 5-inch disk, and put her in my 220.....I put her into a 240 in mid September at 13-inch disk, and now she is almost 16-inch disk!!!....I dont think I can keep her much longer as she is a pig, eating MP, NC, SS, Krill, salmon or trout strips whatever......I dont think I have read about one getting this big this quick!!

Hi,my Pearl male pups grow faster than the females and are more aggresive feeding .
They grow about 1" disc larger than the females in about 6 months.
I have bred a lot now and no female fish has ever outgrown the males of the same litter.
Cannot speak for other species in young fish but I find the male fishes in most rays I have kept more dominant .
This only is reversed when the females are pregnant .
Then they become highly competitive
