HI all, so about a month ago, I added a new betta to my 5 gallon aquarium, his name is Kratos. I got him from Petco the day they brought him in. He is very active and peaceful, have never seen him flare and shares his lovely planted tank with 4 Amano shrimp and a Mystery Snail. He loves swimming and and exploring. He has a mouth deformity, but that just makes him a bit extra special. Has no trouble eating or going up for air. A week or so ago, I noticed he has a white patch around his eye. He doesn't seem bothered by it... but could he be hiding any pain or symptoms? He has no loss of appetite, loss of color, loss of energy, nothing. My water parameters are all 0, PH around 7... any Ideas?
