Today I noticed some pineconing on my betta's head. It's not the first time this has happened though. The tank is 10 gallons and I had it divided between 3 bettas. One betta had the pineconing on his head like her, but I moved him to a different tank, added some aquarium salt, and he got better. The other betta passed away (She might of had it and I didn't notice before it was too late). I don't think it's dropsy because my other betta healed, but she looks worse than he did. Any ideas of what it might be? The pineconing is only on the head and she's a little lethargic but still eating. She's really fat but she's always been really eggy, so I don't think it has anything to do with her pineconing. I would take pictures but my camera doesn't work at the moment.
