Tiger shrimp losing their stripes

[grespania]

My 3 generation of tiger shrimp lost their strips. Anyone experience that?

Too much inbreeding.

i do not understand inbreed. But I only keep my tiger shrimp in my nano tank. The water temp is cold. About 22. Will that be the cause?

Breeding between closely related individuals, called inbreeding, results in more recessive deleterious traits manifesting themselves. The more closely related the breeding pair is, the more homozygous deleterious genes the offspring may have, resulting in very unfit individuals.

Basically you wouldnt have kids with your own family in real life, the closer to your exact blood you breed/reproduce the more likely you are to have an albino offspring and/or any other such unfortunate traits.

Same goes for fish, breeding within the same family will loose colouration, even size i have found. Its best to sell a brood/fry batch and get in more with the money you could make from selling them, this way repeateadly doing this will enable you to breed them and keep the colouration. It's also healthier for them this way too!

Guess the genes of the parents is not strong n water condition not optimal.
