Ooh my gosh! I totally didn't think about that! I mean i thought about it when we got her and one day her belly seemed a tiny bit smaller but not too much. Also around that time one of our males started building a bubble nest. Lol They can keep hoping though cause i'm soooo not ready to breed them nor do i have the setup.That is a girly belly! You can tell the difference because her lady tum swells down low instead of out to the sides- this is her egg sack which is filling itself up.
Over time you will see a little white spot appear below it which is her egg spot and a sign she is ready to lay, She will either lay them (and likely eat them) or her body will reabsorb them when her cycle goes back to normal.
Keep an eye on her belly if you are truly worried, if she goes off her food or becomes lethargic she may be egg bound (epsom salts is a good way to help her lay if this is the case) but other than that it is just a regular part of being a lady betta.
that i think about it both females have an egg spot and are super active. Boy do i feel silly!
Thank you so much for the help!
