So one of my betta's gills is stuck open. Here's what happened...
He's been under the weather and I found out it was because bad water, so I had to switch to spring water and restart the cycling. 3 days later, all seems well. He's regained his appetite, he is more energetic little at a time, and even his face (that has remained dark for 2 weeks now) was lighter in color again today.
Thing is... yesterday I was feeding him, and 2 pieces of betta bites got stuck together in the tank and the dumb dumb went straight for them. Within 2 minutes I could see his gill had gotten itself stuck open (his right gill)
I thought... well... I saw it happen, it's just the food... maybe he'll fix it by this morning.
This morning? Nope.. still inflamed. So I isolate him in a 1/2 gallon bowl cuz the little bugger doesn't want to sit still for me to look and see if there is something lodged in there (his tank is a 5 gallon with TOO many places for him to hide when I need him not to)
And I took a flashlight and can see clearly into the open gill from behind him. Nothing in there... the inside is a pinkish fleshy color, but nothing obstructing it....
