I recently bumped my aquarium temp from about 77' to 79' and out of nowhere my tetras started getting pregnant. At any given time one would be just pregnant (you can just see the swollen belly) and another would be full-blown-about-to-lay-eggs pregnant. I turned the temp down two days ago and haven't seen a pregnant one yet. I'm wondering about the correlation there. Does temperature matter?
And as barbaric as it sounds, I'm sure all of the fish were happy to have some extra food that week.
And it was also nice to see who is male and female and look at behavior patterns of the genders.
