Hi there! I am new to these forums and seeking help for my betta fish Axel. Last weekend I was out of town and had my brother watch over Axel till I got back. When I arrived Sunday morning after being gone for less than two days, I noticed something odd about Axel. His eye was bulging out!! Frantically, I searched the internet and came to the conclusion he had pop eye, though I haven't been able to find a cause.
I immediately changed his water in case of contamination of some sort. Today, I noticed a white patch is now present somewhat on and below his pop eye. If anyone has any suggestions for what I should do to help him, they would be much appreciated. I would also like to point out I saved Roxas and Axel from my friend who was going to trash them because they lived passed their three month expectancy (I got them in April). Roxas passed away due to complications from a deformed gill a few weeks ago.
I am a college student on a tight budget so please keep this in mind when making suggestions. Thanks!
