Convict fish has been in a hospital tank for 10 days. This fish has had frayed fins for at least months and possibly years apparently (fish was a rescue). Have treated with 1TBS salt per 5 gallons with daily dosings of M1/M2 and every other day 80% water changes. Water temp turned up to 84F. Have given the fish twice daily methylene blue baths as well. There has been absolutely no improvement in the 10 days. ??? Need opinions for the next phase of treatment. Thank you.
