The Puffer Forum

Okay, I've been off this forum for a very long time.
To answer the questions above, I dont have my testing equipment for my tank, its been stabilized for over a year and I've mislocated it. Its a 25 gallon tank with 2 figure 8 puffers. I feed them once a day (blood worms) and do 25% changes once a week. I have not done anything differently in this past week. My aquarium has been set up for close to a year now?

I keep trying to get a picture of this but I cant get one. But one of my puffer's eyes has been closed off and looks as if its concealed by a giant red swirl. It honestly happened over night. I dont know what condition the eye under neath this mass is, but the bulge looks almost like a giant red swirl thats covering his eye. Its not something external though, this looks like something that developed in his eyelid or whatever they have D: I cant tell if this is a worm that made its way into his eye but I am so sad :"""( He's acting perfectly fine, eating well, swimming strongly but he kinda runs into things because he can only see out of one eye!!
The other puffer in him is just fine as well. I dont know what I can do...

That sounds awful. Now, more than ever, you need those test kits -- find them or buy new ones. I'm not sure how else a swirly eye can be treated except under excellent water conditions.

+1, excellent insight for a newcomer here, Lola!
