I’ve had my black Galaxy koi betta for about 2 months now, I’ve noticed lately that his dorsal fin is getting smaller/shrinking?? Could this be some type of fin rot?? I always thought his fin was just folded up but his other ones fan out just fine unlike his dorsal fin. Hes had ich/been treated for that in the past, and I’m fairly certain he has early stages of blindness despite being less than a year old- poor thing has had quite a ride already. (He has also injured his dorsal fin before, but seemingly light scratches) What’s happening with this little guy??
