Egg-laying season?
 
I have black skirt tetras, neon tetras, zebra danios, and a female betta. I've been noticing that about half of all my fish, all types including the female betta, are getting a little fat. They are otherwise happy and healthy, and my water parameters are excellent - ammonia 0, nitrite 0, nitrate 10. Are they getting ready to lay eggs? I'm not attempting to breed any of them, but I was just curious. :)

Temperature changes, barometric pressure and other subtle changes that we don't feel are often stimilus for spawning. I have read a lot of different articles that say many species will spawn right after a storm as the barometric pressure changes drastically from low to high or visa versa.

That makes perfect sense - we just got over some wet weather here and it is starting to warm up a bit now. It's almost humorous - I now know which fish are females since most of my species show now outward signs of gender!
