Why I believe that Texas reproduce asexually...

  • We are currently upgrading MFK. thanks! -neo
Just to make clear, all 5 you bought were female? Bad luck. Apparently you should have bought 6! I bought 6 cons a while back just hoping to get a pair and wound up getting 3 of each. You never know what you will get when buying them young.

fish have been known to reproduce without the opposite sex

Only Amazon Mollies, which are all female clones (males dont exist).
Most Livebearers can drop several batches of fry without males being present, but this is from stored sperm, so their was a male involved.
 
Few creatures as complex as a fish actually reproduce asexually, most of the true asexual reproducers that high on the evolutionary tree I know of are lizards.

And yes, it was the five I bought that were all female. Just got back from the LFS and traded them in for a bigger sized Texas, which looks male to me THIS TIME. Statistically speaking, I should NOT play the lottery as I appear extremely unlucky. Still can't believe that out of 5 fish there wasn't a single male...

Female members of a crayfish species called Marmorkrebs can reproduce asexually.

I thought they were all females? I was under the impression that there were no males.
 
The odds were 1 in 16 you'd end with all the same sex 1 in 32 all female, so really not lottery numbers.

First fish you have a (1/1) chance of a male or female. Second fish you have a (1/2) chance of it being the same sex as fish one. 3rd (1/2), 4th (1/2), 5th (1/2)...(1/16).

For all female instead of a 1/1 it would be 1/2 as well...
