It looks like an Aeromonas infection (bacterial septicemia). If you can post your water permaters ammonia, nitrite, nitrate & Ph I'll recomend a med. Do large water changes and substrate vacuming. Keep the filters clean and use prime or a similar product (for redox reduction). Keep the tank clean and add 1 tablespoon of salt (provided you have no salt sensative fish) per 5 gallons of water in the mean time.


Treat with Kanamycin or even a combination of Kana & Furan 2. Remove the Chmi-pure before treatment. Both meds need to be used at full dosage as directed on the package. If you can't find the Kana right away start with the Furan 2 and add the Kanamycin when you get it. Furan 2 is not absorbed so it is only usful topicly, the Kanamycin is absorbed and is what you need if this is systemic. If you start with Furan 2 and it resolves no need to add the Kanamycin. You may need both however.
