Hi! I just noticed last night while doing a water change that my Betta's fins were white. I can't tell if this is just my Betta's coloring and fin shape or if it is fin rot, i would like to know before i start medicating with salt and things like that but would also like to start ASAP if it is fin rot. My Betta lives in a 10 gallon tank with no other tank mates, silk plants, a sponge filter and a heater that is always set to 78/79 degrees. I try to do 10 percent water changes once a week but I will admit that every once and a while he will go 2 weeks without a water change. The first picture is from about 2 months ago and the second picture is last night. Any help would be appreciated. Thank you!!
