I'll make this short and sweet, I keep my female betta in a 14 gallon tank with 3 male swordtails and 3 catfish (they all seem to get along fine, no fighting). However since adding the extra fish my female has decided to eat everything in site... pellets, flakes (for the swordtails), etc. There is nothing she won't eat... as a result (I think?) she has developed a huge belly.
That's a photobucket album of a bunch of pictures I snapped, there are crappy pictures and some good ones but I left them all incase someone found something useful.
There is an evident white thing at her vent, if that means anything. She is also defecating on a normal basis.
If it is obesity, should I remove her from the tank while I feed the other fish and simply give her a few pellets a day?
