Medications
By Liv

The following list explains how to use the most commonly recommended cures/medications. Remove carbon prior to dosing the water with medications and turn off UV sterilizer. If feeding medicated food only, add fresh carbon to remove residual medication from the water.

Salt

Meds for Parasites

Rid Ich (combination of malachite green and formalin)

Quick Cure (formaldehyde and malachite green)

Praziquantel (Sources: PondRx, Drs Foster and Smith, Goldfish Utopia)

Flagyl (Metronidazole)

Metronidazole is a bactericidal antibiotic effective against anaerobic bacteria and certain protozoan parasites including Hexamita. It also reduces inflammation in the GI tract. Seachem makes a powdered form of Metronidazole that can be dosed in the water and can be fed in a medicated gel food.

 

Jungle Anti-Parasite Medicated Fish Food

Meds for Bacterial Infections

Medi-Gold (Medicated food containing Ormetoprim, Sulfadimethoxine, Kanamycin and Oxolinic Acid)

Metromed (Medicated food containing Metronidazole, Ormetoprim-sulfa and Oxytetracycline)

Tricide Neo or Neocide 3 (Neomycin based short term bath)

Shake and Bake method:

Spray method:

Repeat every day or every other day for AT LEAST THREE treatments.

The mixture can be reused (filter thru coffee filter if there's too much debris). Store reconstituted tricide neo in a covered, child-and-animal-proof container in a cool, dark location. Discard reconstituted tricide neo solution after one week.

Kanacyn (Kanamycin or kannamycin)
Broad spectrum water antibiotic. Can be bought in many forms. Aquatronics is common source but is rumoured to be going out of business. Aquatrol is another a source of Kanacyn capsules or it can be bought in powder form (kanamycin sulphate). It can also be made into a medicated gel food.

Maracyn (erythromycin)
Used for gram positive bacteria generally, but found to be effective against some gram negative infections such as flex as well.

Maracyn 2 (minocycline)
Used for gram negative bacteria generally (Most fish bacterial pathogens are gram negative). Is affected by light as well as water hardness. See UF IFAS publication: Use of Antibiotics in Ornamental Fish Aquaculture

Maracyn Plus (sulfadimidine and trimethoprin )
Water antibiotic effective against gram negative bacteria (Most fish bacterial pathogens are gram negative). Marketed by Mardel. May be preferable to the other two Maracyns as resistance to erythromycin (maracyn 1) and minocycline (maracyn 2) may be increasing.

Antibac-Bath (Nitrofurazone based anti-bacterial bath)

Note: For our friends in Canada Mail Order Pet Supplies and The Fish Sempai carry some of the products listed.

Other Medications

Maroxy (Sources: Most local fish stores) A chloride oxide compound used to treat true fungus.

Clove Oil (Sources: PondRx) Used to sedate the fish, so you can treat it.

Note: Finquel (MS-222) can also be used for sedation (or for euthanasia). Sources: PondRx.
