Doing some reading and making my "Spreadsheet o' Fish" for my future tanks and stocking plans.
I have read that livebearers like mollies, guppies and platies will cross-breed if in a tank together.
But I've not found info on egg-layers like tetras doing this naturally (ie just swimming in a tank with other species).
Does anyone have any info or links on how likely this would be to occur?
I'm thinking that if you keep a proper school that the likelihood of them looking outside their own type would be rather rare. That is assuming that in a random selection of fish, you would likely get some males and some females in a school and not an all one gender school.
