My first sick fishy question :(....
Our half moon betta, who we've had for about 2.5 weeks seems to be turning more and more into a crown tail.
I'm worried he may have fin rot, but then when I look closely, I don't see the dark edges. The fin is just receding between the rays. There is one ray on his under fin (?) that has a little curl to it. The receding fins has also recently spread to his top fin.
If he doesn't have fin rot- which he may, can high ph cause this? And if so, what causes high ph? my tap water is 7. Do you ever see fin rot without the dark edges?
5 g filtered & cycled tank
Nitrates=less than 5
50% WC each week. I use stresscoat with conditioner for all water changes and top offs.
I did just realize that the filter needs changing, so I'm going to do that with a water change tonight.
I also just bought aquarium salt in case I need it, but will wait for replies before adding.
