Popeye Betta

Question
Hi, My betta has what I think is pop-eye.  I have had him for 16months.  Abouta month ago Basil's left eye started with a bulge above it and is now the whole eye petruding out and glazed over.  It is huge and the scales around the eye are sticking out.  I haven't done anything out of the ordinary for this to happen.  Basil happily lives in a huge tank with a filter, light and thermometer.  He is the best looked after fish you'll ever meet.

I'm really worried about his eye and would like to know what to do about it.  I don't want to loose him!!

Answer
hi stephanie

Make sure you check on him. Also check your amonia, ph and nitrate level in your aquarium. If anything get wrost let me know..
