Treat the gut and the bacteria that move in behind it.

Fish Zole (metronidazole) is the standard treatment for internal protozoa such as hexamita, and Fish Dox (doxycycline) handles the anaerobic and gram-negative bacteria that take advantage of a damaged gut. Using them together is how experienced discus and cichlid keepers treat wasting disease. The 100-tablet Zole bottle covers several full courses.

What's in the pack (2 bottles):

Fish Zole 500mg, 100 tablets (sold separately at $109.99)
Fish Dox 100mg, 30 tablets (sold separately at $49.99)

Use it for:

White, stringy feces and a swollen belly
Hole-in-the-head and lateral line erosion (hexamita)
Fish that eat but keep wasting away
Discus, cichlid and angelfish gut problems
Secondary bacterial infection after parasites
