I did not know that Fish Vets existed until I met Richmond Loh.
I am very grateful that he happened to be working in Tasmania when my gold fish became unwell in 2005. I quickly lost 60 of my 100 fish which lived in a large pond. He set up his portable lab, obtained samples from fish of different sizes and diagnosed the problem (gill fluke).

Diagnosis included a likely cause for the infestation (repotting of water lilies with soil from cow paddocks). Treatment included removing that soil, vacuuming the pond to remove excess silt from its base and treating the water with trichlorfon (with appropriate protection because of the danger of this product). This was successful and my fish have remained healthy since. Their numbers have increased to 80.

I highly recommend Dr Richmond Loh if you need medical help with your fish.

Those of us who love our finned friends as much as our other animal companions know how heart breaking it is when they get sick, and no one seems to care, or seems willing (or able) to help. When one of my beloved seahorses took ill, I was beside myself – I didn't know what to do for her, no over-the-counter medications were appropriate, local vets weren't able to help – one even scoffed at me when I asked for assistance.

"A fish?? We don't treat fish." What are you supposed to do, just let them die a miserable death? That's just not acceptable in my opinion, my finned friends deserve so much better, but where do you turn to?

Fortunately for me, and my beautiful seahorse, the fifth vet I called gave me Richmond's contact details. What a relief to speak to someone able to help! Someone who took the problem seriously, spent the time to get all the facts to make the right diagnosis, and prescribe the right medications to fix the problem.

Despite being on the other side of the country, within hours of speaking with Richmond I had a treatment plan and the medications I needed, and my little one made a full recovery

I've had to call on Richmond for help since, and on each occasion he has done an amazing job of helping me with my seahorses – we had an illness that lasted nearly 3 months, but Richmond never gave up, doing everything he could, including taking swabs of the infection to lab-test for the precise bacteria plaguing my seahorse to ensure we got the best medications we could.

When people tell you, "It's just a fish and nothing can be done." Don't listen to them – give Richmond a call. Something probably can be done to help them, you just need to speak to someone who knows what that thing is.

There are treatment options available when you know who to ask. I could never put into words the peace of mind I experienced when I found someone who could help me with my seahorses. Knowing that whatever ailments they may get, Richmond is just a phone call or e-mail away makes so much difference.

I believe all animals deserve the best veterinary care we can provide for them; thankfully there's a vet out there who can, and will, help us take care of our fish when they're ill. I'm sure that as long as I have seahorses, I will remain a client of Richmond.
