Check with yours water parameter again. Ph should be too low

By pointed tail, do you mean clamped fins? Or are the tails pin-tail shaped? See this picture for what I mean by pintail guppy:

If it is a case of clamped fins then your fishes are suffering from a disease, probably bacterial in nature. You should always raise the fry separately from the parents as they will attempt to eat the fry if given a chance.

If they have pintails then one or both parents have the pintail gene.

Thanks for reply.The first batch i had the frys with my moscow frys in a seperate tank so nothing happned to them only the red were effected and all died.its not the same as in the pic its clamped thin and pointed in the end its from the day they are born.

the water should be too cold has i had encountered this b4.

Pappu, are the red parents in the same tank affected too? Have you done water tests for nitrite, nitrate and ammonia?

The temp is 24 degrees.Yes they were in the same tank before they died.No test done,But had added some moscow frys with them they were ok,only red ones died.

Either the temperature or the ph change is too big of a inflaution causing this issue. get coral chips to buffer the ph i would recommend that.

I believe that they might have been stressed out by the Moscow fry, or the red fry were carrying a genetic defect that would ultimately lead to their death. There are cases where certain genes are lethal when "combined" together via cross breeding.
