| fish breeding
when you go into a pet store the same species of fish are usually kept in the same tank, does this mean they are all one gender or they just arent breeding? or maybe i just cant tell if they are pregnant
ex: guppies and bettas are separated but into male and female but all others species seem to be mixed but dont seem to breed
im asking because id like to not cause any unwanted pregnancies or if i do i know what to do
i know each species has certain requirements in the tank so i can google that |
