Bloodfin Tetra Down :(

[Djs7137]

I have a 10 gallon tank stocked with 4 Bloodfin tetras and 4 corys. I went away to college over the winter and had my dad take care of my fish unfortunately he didn't do a good job. One of my tetras has died...(I had 5 now 4 .....)
and now one of my tetras has almost like a small tiny cotton ball on his lower jaw and looks like his top jaw is almost....being eating . I do water changes every month and the water lvl's are fine. Any idea what this "disease" is on my bloodfin and how i can cure it !!!!!!!!




Thank you,

It sounds as though your fish might have columnaris (often called 'mouth rot' or 'mouth fungus', but it's a bacterial infection).

You could try a course of salt baths (1 tablespoon of aquarium salt in a gallon of water every day for 30 minutes) or Pimafix; if that doesn't sort it out you may have to use antibiotics.
