Disease treatments
an overview of how treatments work, why they often don't work and why they sometimes kill fish.
Disease treatment basics
When you have fish health problems, this guide details the steps to take, and what to do if it isn't possible to make a definitive diagnosis.
Antibiotics
are an important treatment option against bacterial diseases if they are used properly.
Injecting antibiotics
gives the best results against bacterial infections - especially when dealing with severe cases.
Antibiotic baths
and dips are not generally as effective as antibiotics given by injection. Baths and dips may however, be useful for surface infections.
Dimilin
Effective treatment against anchor worm (Lernaea) and possibly fish lice (Argulus)
Medicated food
is a useful option for treating bacterial disease, but it does have some disadvantages.
 Topical treatments
can be very effective against bacterial diseases - especially when used in conjunction with antibiotics
Chloramine-T
Can be tricky to use - but is effective against some parasites - it can also assist in gill problems.
Copper
a treatment for marine parasites.
Malachite green and formalin
an all-round anti-parasite treatment, especially good for white spot.
Organophosphates
the "bad boy" of treatments - but the best treatment for the "difficult" parasites such as Argulus.
Potassium permanganate
an effective treatment against many parasites, especially Trichodina. Can be useful for bacterial problems and disinfecting nets etc.
Quaternary ammonium compounds: (QACs)
useful for gill disease - as it acts as a mild disinfectant with detergent action to remove debris.
Salt
The fish keeper's standby for parasites, gill congestion and osmoregulation problems. It's safe, and cheap
