Still have Popeye

[Drift]

I'm leaning towards injury because he's a nut and has become pretty neurotic.
It is just one eye and I'll try to grab a picture and post it in a few hours. My camera batteries or on their last leg and not holding charge anymore. (They die overnight. ;-;)
I used half of a tablespoon for 5 days. Slowly acclimating him to it over a couple hours.

When it is just one eye as you suspect- it is most likely injury related, however, secondary infection often happen-it also can be a tumor that is pressing on the back of the eye causing it to bulge.

Epsom salt 1tsp/gal up to 3tsp/gal can help with symptom of the swelling if it is not a tumor-
You may want to try a larger dose of the Epsom salt and keep him in it 24/7 along with 100% daily water changes and see if you can get the edema/swelling to decrease some-often they can lose the eye-but can still live a normal life-also, dimming the lights can help make him feel more comfy.

Is he having any other symptoms or is it just the eye? appetite okay-how old is he or how long have you had him?

Thank you for such awesome help. <3
I got him around August, so not long. The only other thing he does is he started to tail bite. They started around the same time, so I think he has trouble seeing and keeps nomming his tail. He's gotten a little more aggressive too. He's eating like the typical piglet betta.
How long should I try to the Epsom salt for?

I would do a full 10 day treatment.
