Endlers (more Males Or More Females)

[5teady_2012]

HI, after experimenting with the temperature whilst breeding my Endlers over the past several months (approx) here is what i got... thought this might be useful to some who have recently asked related questions on this...


Heater was at 26 degrees for (first Drop)

Female 1 - dropped 24 fry - outcome of sex - 4 males - 20 females

Female 2 - dropped 20 fry - outcome of sex - 5 males - 15 females

Female 3 - dropped 21 fry - outcome of sex - 2 males - 19 females

Female 4 - dropped 29 fry - outcome of sex - 6 males - 23 females



Heater was at 28 degrees for (second Drop)

Female 1 - dropped 26 fry - outcome of sex - 5 males - 21 females

Female 2 - dropped 20 fry - outcome of sex - 4 males - 16 females

Female 3 - dropped 23 fry - outcome of sex - 3 males - 20 females

Female 4 - dropped 31 fry - outcome of sex - 6 males - 25 females


Heater was at 24 degrees for (Third drop)

Female 1 - dropped 26 fry - outcome of sex - 11 males - 15 females

Female 2 - dropped 23 fry - outcome of sex - 9 males - 14 females

Female 3 - dropped 22 fry - outcome of sex - 7 males - 15 females

Female 4 - dropped 30 fry - outcome of sex - 14 males - 16 females

Got lot more male when the temperature was lower, this is off my personal breeding sheet and just what i have come up with.. ovbiously it will be diffrent for others but maybe this helps to indicate that lower temperatures can help to get more males..

Are your endlers mixed with guppys mate that is pretty large drops for endlers i heard the maximum you will get from a endler is around 15

No m8, not mixed with guppies these

just my females have had lots of drops and they are pretty big, they are all one color and no sign of ever breeding with guppies, they have certainly not been in a tank with guppies while have bred them.

I have small endlers that only drop between 10-20 but when the other 4 was youger like them, they only use to drop small amounts.

I'm assuming that you didn't have a 100% survival rate though.
So out of each drop, these were the ones who made it far enough to be sexed.
It might be that the lower temps don't produce more males, but that males are more likely to survive in lower temps.
Not that it makes much difference -- if your objective is to get more males I guess it doesn't matter which way round it works!
Interesting stuff. And it makes me wish I had room to start breeding fish!

Very interesting findings.

Whilst I haven't been so precise with recording exact details I would say that my experience with endlers would bear out these findings too. I have two tanks that are cold water (no heaters at all)and the fry tend to be a higher ratio of males to females than in my heated tank that is set to about 25 degrees.

I guess this would replicate what you would find in nature. The ideal ratio I guess is 1 male to 2/3 females and in their natural environment in Venezuela they would live in warmer waters, which would produce the optimum results.....

What strain of endlers do you have by the way?
