Hi and thanks for reading. My wife has a blue betta that we think has gotten fin rot. I have attached before and current photos. She has cleaned the tank and then separated the betta as well. She has been using an antibacterial treatment and aquarium salt. The fish started doing better at first, but now has gotten worse again.
If anyone has ANY suggestions, please let us know ASAP! This is one of her first fish and she loves it a lot.
Thanks in advance!
