Would like to hear opinions from bros here..

1) Is it genetics?
2) Is it birth defect?
3) Is it keeping methods?

Care to share all your views?Scenario...two fish of same parents bought by different owners.One grew up to be nice and well formed,another hardly grew an inch.One was kept in green water...another clear water.Feeding methods are same.

If it's keeping methods...care to share how bros here with success growth rate keep their prized possessions?

whats your opinion?

the grew bigger one kept in green water or clear water ?

is the 2 owners doing the same thing ? same amount of food, same water change, same amount of water and what else same ? Since 1 green water, and the other cw, then you have water parameters as your unknown factors.

Like mountain asked, what is your opinion from what the information you got ? It's not easy for anyone of us to reply without the 1st hand detail information like you.

The one that grew bigger is in the green water..keeping methods not too detailed...all i know they feed the same type of food and the number of feeding in a day.Water changes is done weekly basis.That is all i have for the info.

We should also note the stocking level.

Bro,only two fish kept in a blue tub 3ft x 2ft.All fish kept are not more than 5 inche in size so far.

not enough info, can't help you.

The fact that a certain Ranchu remains much smaller than his brothers and sisters from the same spawning can be caused by :

1) genetics
AND
2) the way it is kept or developed

1) genetics :
- certain bloodlines always stay smaller than other bloodlines
- in every spawning, no matter what bloodline, there are always a number of babies that remain smaller than the rest of the babies. The breeder will always keep, develop and breed the bigger, better Ranchu himself.

When Ranchu remain smaller because of the genetics, then it is impossible to correct this in a later stadium.

2) the way the Ranchu are kept or developed

This can be a little corrected when they are kept in better conditions or fed better food etc.

I hope this is a satisfactory answer to your question.

Thanx Geert for the insights. So...i guess this means the fish that is smaller can be flushed down since it can'y be corrected.Wouldn't want to waste time,effort and cost to try grooming the stunted fish.

Ranchu_lord, how about some pictures of the 2 fishes for further comments?
