Size difference in siblings
Can you believe that these two flavus came from the same spawn? That little runt has not grown while the others are much bigger now.
No one messes with it, but I don't think it was meant to be.

Re: Size difference in siblings
That's amazing
Wonder if it'll ever get any size. I've never had one that was that much smaller than the rest either.

Re: Size difference in siblings
That is definitely strange. You should update us on it if it grows....or if it doesn't. Maybe it's dwarfism?

Re: Size difference in siblings
I'll update if he survives, but I'd be surprised if he did. He's a little bigger than newly spit, but not by much.
I thought about separating him out and feeding him to see if he grows, but I don't know if I should do that because he's obviously got some sort of problem. At feeding time, all of the others rush to the top and wait for the food while he stays at the bottom. I know he gets some to eat, but not as much. Even though he isn't getting as much to eat, he should still grow at least a little bit.

That is strange!
That's a lot of size difference!
Well, I guess sometimes nature works in strange ways.

Re: Size difference in siblings
I had a couple of male Rusties that showed the same type of size discrepancy. They were both about an 1 1/2" when I got them but one of them didn't seem to want to eat when everybody else was pigging out. It grew maybe another 3/4" but was still half the size of the other. I had always thought that it had some type of problem swallowing. It seemed to wait around looking for smaller tid bits.
Re: Size difference in siblings
I have few fish with some size differences but nothing like that. In nature I'm sure that one wouldn't have survived this long.

Re: Size difference in siblings
I think normally most breeders would cull the tiny one.
It is done naturally in the wild.
That is a huge difference.

Re: Size difference in siblings
I put some Obliquidens in my 90 gal, they were about 3/4 to 1 inch, one of them is twice the size of all the rest, and on one of them hasn't grown at all. The others are all about the same, bigger than when they were put in there, but all growing at about the same rate.

Re: Size difference in siblings
I saw the size difference in my old tank too. I blame it on recessive Gene, It show up in some of off spring.

Re: Size difference in siblings
That little thing is still about the same size and now one of the females in that brood is holding already. I don't know why the other fish don't bother with it.

Re: Size difference in siblings
I have some Obliquidens with big size differences, too. There's one that's HUGE, and the others are pretty much the same. There's one that doesn't seem to be growing much at all. I guess it's just genetic variation. I am interested in whether the really giant juvie turns out to be male, though.

Re: Size difference in siblings
Aura, in the wild you would only expect 2-3 fish out of each spawn to grow to maturity, so these smaller sized fish would surley be eaten,,,
its a "grow big,fast,,,or be eaten" deal.
Nice pictures!
What are you using these days for a camera?
Cheers,Larry

Re: Size difference in siblings
Thanks Larry. I took these pictures with my old Canon PowerShot A540. I've also been using a Nikon D60, but it requires camera smarts that I don't have.
