Help! Bubble attached to tetra eye.
Hey everyone, I just noticed this morning that two of my Pristella Maxillaris Tetras have a large bubble attached to one of their eyes (the eyeballs appear normal however). I've listed all my parameters below as requested. The only thing new to this established tank are some live plants introduced 2 weeks ago and I switched my feeding schedule from one a day to two smaller meals per day. All the fish are well established in this tank which is 3 1/2 years old. Not sure what the bubble is or what could be causing it. I'm just finishing up a 75% water change but have not added any chemicals or treatments to the water. Oh, and I have attached a photo below that I think shows the problem well enough, I hope. Need to get a fix and a handle on this ASAP. It's got me really worried. Thanks SO MUCH for any assistance.

Pop eye isn't a disease in itself but a symptom of an underlying condintion. It could be bacterial or stem from poor water quality. It seems like you do frequent and large water changes but the fact that you have ammonia present in a tank that has been established that long is a little troubling.
Can you isolate the fish that are affected? You can try 1 TBSP of Epsom salt per 5 gallons in a QT tank and do another half dose on the 3rd day with frequent water changes.
I hope you're able to help them out. Good luck.
Yeah the ammonia spike, which is unusual, has me puzzled; especially with live plants. I've never had ammonia spikes in the past and the only thing I can figure is my increased feedings might be leading to the spike. I'm going to take your advice and QT them in my isolation tank and treat them with salt accordingly. I'm going to return to my normal one feeding per day routine and watch my water parameters closely over the next week to see if things settle down. Thanks Romad for the help!
