my betta fish has been going through some tough times. My five gallon tank has a heater kept at 78, a low flow filter and a light. Recently I moved back home from college and had to transport him. I also got him some driftwood which I boiled for an hour before adding to the tank. When his new tank was reset up a bacterial bloom clouded the water. A kept testing the water and ammonia was 0. After his condition worsened i quarantined him him in a smaller tank to tend to him.
Due to the look of his fins and color I suspected fin rot was setting in but just today I noticed small red dots on the bottom of his tail (seen in photo above). What are these red dots? Please help this poor guy I want to treat him but I’m not sure what to us yet!
