Stunted Fish Identification Options

[Hamad]

How big is he? I mean in cm or inches?

From what I understand a stunted fish usually have large eyes and fins that do not look proportioned with the rest of the body, sometimes the body shape also looks deformed in extreme cases.

9cm from head and tail, about this picture's size.

My guess - Don't look stunted to me. But also probably not 1 year old.

Body and hump not developed yet. Also the size and shape of the fin looks more like a 6 month old ryukin. Would be about right for 3 inch.

Got prize or not if I guess correct ? hehehe

Thanks for your reply. I want to give your delicious food but you are too far and I don't know the answer. He has breeding mark on his fins and chase another female and makes me guess one year old.
Is it right?

[Hamad]

I totally agree with Kencheng, judging the size and how it looks in the picture it doesn't look stunted. It would be good if you keep track of the size within the next month or so and see if it grows or not.

Maintain good food [I give up to four meals between 8am to 4pm] and of course water changes and enough space, it should grow. Good luck and keep us updated!

Snowfire - from experience - some baby goldfish 6 months already ready to CHIONG (breed) already!

Maybe someone with more breeding experience can comment?

In Singapore, some goldfish can spawn when they are 5 to 6 months old. Even Japanese ranchu imported into Singapore from Japan do spawn that early. Only problem is fries are too small and has lots of defects.

BTW the fish shown is beautiful without obvious defects which is a plus point.

So my fish is younger . From Now on , I will record their length.

how about an example of a strunt just to add to the confusion!

This is a follow-up to Forrest's explanation to Eye Ratio.... Sorry that the server lost this image.

This is the comparison between a normal and stunted ranchu (thanks Tan for contributing his fish as model ):
(Notice the fins would be out of proportion too)


The pupil (black area) usually give a very big hint to the stuntedness.

But contrary to what I have read from other places, you can't tell if a fish is potentially stunted. Once you see a fish stunted, it is already too late to rectify. But this illustration would be useful to prevent you from buying stunted fish though ;)

Hello, my first post. A very informative thread, thank you!

So a runt is genetic? Then that trait could be passed on to offspring and two runts would produce more runts? Would it not be commercially viable to actually value this trait rather than cull it and so produce a 'dwarf' line of goldfish?

I'm thinking that given the restriction of space and tendency to overstock, a miniature type of goldfish could be very successful. Like miniature dog breeds for people who live in small apartments, miniature goldfish would be more preferable to the larger ones for many people. And easier to look after. Also, larger eyes make for more cuteness and appeal! ;)

Or is the runt's reproductive ability also runted and so this is not possible? ;)

I dont think so. I am of the opinion that offsprings of two runts can produce a normal goldfish.

Haha,as far as I know, goldfish hobbyists are looking for large ones, given the choice.
But, given a choice, I would prefer a mini bull terrier over a bull terrier.

Hey, both pics are of the same fish.

So is this fish a runt in the first place or has it been stunted by Ah Tan?

If Ah Tan's hand remain the same in both photo then the body did not grow and only its eyes have enlarged
