I'n keeping cherryshrimps for about a year now and i noticed that they lose color fast whan you breed them :undecided The group i started out with where realy deeply red and although i bought some for fresh blood, the ones i have now all look like the males of the first group :( How often shout you ad fresh cherry's to keep the color right?

Hello ganesha!

I think it's more a question of nutrition and water conditions than genetic reasons. Cherrys need a large variety of biochemical compounds to keep their colour. For that reason, fresh algae are the best nutrition for shrimps. Do you have algae in your tank? What do feed your shrimps?

I'm afraid i don't have any algae at all in my tanks. I feed the shrimps peas, carrots, cucumber, algae tablets, shrimppellets,spirulina plankton, cyclops (both frozen) sealettuce(also frozen) and sometimes nettle. What should i feed them and what waterconditions should i provide to keep them nicely red?

You seem to feed the correct food. Have you added in new cherries? You might want to wait a few more generations and see the difference,

ganesha, what is the PH and temperature do you keep your cherry shrimp?

Apparently, acidic water and cooler temperature best bring out there color.

I normaly don't check my ph but i will tomorrow. The water is a bit warmer than normal know (23/24 celcius) because of the summer. Normal is 21/22 celcius. I added some fresh blood a few months ago so i should see a difference by now. I vissited a friend today and saw her cherries, mine are about 25 % of hers when it comes to coloration :(

You may want to lower to 6.7 or 6.8 to see if there is any effect. The drop in PH may not have much/any influence on the color of the adult but will affect those tiny shrimplets that are growing up.

Does background and gravel color has influence on cherry shrimp color? How do these 2 factor different from your friend's tank?

Yes i think the bottom color is a big influence too. She has black gravel in all her tanks, i have the cherry at sand at the moment. I saw some nice darkbrown gravel last week, mayby i'll switch to that shortly. For the rest my tank is very well planted, so they should feel safe enough

How old are they? If they are juvies, they may take a little longer to color up compared to adults.

They are all of different ages, but al lot of juveniles that's right. But the juveniles in my friends tank where for sure solid in color and already nicely red!
Maybe i should pick out the ones that are deeper red and sell the rest all out and start a new group :undecided

Mmmm.. that might be the reason ?

My PH is around 7.1 and temperature is 27-28 degree celcius and my female cherries seem very red. By the way i also have a dark gravel. Seachem Onyx sand which is dark grey. Even my bee look great !

My cherries al all nice and red again :drummer: I overdoses the planaria treatment and had you do a big cleaning in the tank. Changed the botom color to dark gravel and bingo redcherries!

Tough job ! As good as revamping or re-setup the whole tank. I did the same when i change to a dark gravel .... lol
