Two excellent books on fish health and medicine.

To be acquainted, I am a West Australian veterinarian with special interest in fish and have worked both in the laboratory and in the field, and am a fish hobbyist myself.

You may know me on our new YouTube channel –

I believe that like you, I’ve found that information on fish health, disease and medicine is difficult to come by and is at best, fragmented. This is why I have published two books on aquatic veterinary medicine that I’m sure you’ll be interested in:

Fish Vetting Essentials


Fish Vetting Medicines: Formulary of Fish Treatments

The information in these books are priceless. And do you want to know the greatest thing about the Fish Vetting series is? It has often been said that text books are usually 10 years out of date and that journal articles are 1 year out of date. These books are a ‘living’ document and I regularly edit any pages that need updating and you can download the new pages from my blog –

More information on the books are available by clicking on their links.

The books are available at The Fish Vet’s site (use your desktop computer or laptop to view).

Please feel free to forward it to others who may be interested.

Thank you.

Why remove tumours from fish?

Most neoplasms (cancers) in fish are localised, benign to locally invasive. One issue is that the neoplasm can grow to such a size that makes them weigh fish down, interfering with their buoyancy. Consequently, for fish to maintain their position in the water, they will have to use excess energy. Of great concern in goldfish is that tumours can throw fish off balance, and lead to swimbladder disorders. Another factor for choosing to remove neoplasms is because they can grow but start to rot internally, causing fish to become ill. Some may be prone to traumatic injuries, causing pain and portals of entry for bacterial infection. For internal neoplasms, they occupy space and compress other organs causing them to fail.

Watch some videos of cancer removals in fishes at these links:

Fish Joke for Monday-itis: shark infested waters

During a company’s annual end of year Christmas boat trip, their boat ran aground and they were stranded on an island surrounded by shark infested waters… the eccentric Boss dared any of his employees to jump into the sea … and swim to the shore to get help.

Anyone who survived the swim will be rewarded with 5 million… but if killed by the crocs…2 million will be given to the next of kin.

For a long period of time no one dared take up the challenge… then suddenly a man jumped in…and swam frantically for his life towards shore pursued by a tiger shark… and luckily he made it unscathed.

When he managed to recover his breath… the man, who became instant millionaire, shouted asking who pushed him into the sea….. it was his wife who did it.!!!

And from that day…that was how the phrase… “Behind every successful man…there’s a woman”…came about !!!😜🤣
