I have a betta that I have had for at least a year and when I went to feed him this morning I noticed one eye is swollen, the other one is normal and I do not see anything abnormal with the rest of his body as far as I could tell, he kept turning the other way. I have looked at pictures of popeye and that is what it looks like. Little Meanie has been eating fine as far as I have been able to tell. He has been spending some more time in his little clay pot house recently. I checked his water:
nitrate - 40
nitite - 0
hardness is about 50
He is in a gallon tank and I did a total water change about 2 weeks ago and I rinsed off his gravel in a strainer in the sink then too because I do not have a filter in that tank. I was planning on moving him to a 2 gallon tank this weekend that does have a filter but I do not know if I should go ahead and move him (because of stress) or wait this out. What do I need to do? I am afraid to do a partial water change because I do not want to upset him (he is very tempermental) but I do need to do something about the nitrates. This fish and I have been through it (he jumped out one day when I left the lid off months ago but after a good lecture to him and myself he recovered) and I do not want to lose him now. He is alone in the tank because when I first got him I had him in a 20 gallon with other fish and he killed 5 of his tankmates (hence his name Little Meanie). Thank you for all of your advise.
