Greatly appreciate taking the time to film and narrate these visits! Hopefully in the future you can get an assistant to help film to make things a little simpler for you. I would think anyone interested in becoming a fish veterinarian would jump at the chance to be your assistant.

[@thefishdoctor8746]

Many of the visits are responding to emergencies and is difficult to schedule help. We have a student chapter of the World Aquatic Veterinary Medical Association at Murdoch University locally where I volunteer time with the students who have an interest in fish vetting.

Hi ya love your channel! Where would be the best place on a koi to inject antibiotics? I’m new to your channel so I haven’t caught up on all your videos yet

[@hazell1304]

Ok but the fact that you were so nervous trying to help these fish that you had to film a disclaimer is incredible in itself. Too many people stop caring about animals when they're aquatic and it makes so sad (and angry tbh) I just found your channel but I love it already.

[@HarleysAngel2005]

Thank you! You are amazing! To take the time to film duriNg your tedious and already stressful job.....just out of this world, thank you for your passion and patience... truly one of a kind.

Thanks Dr Loh. I'm on tank water so my Ph is around 5.3. I use crushed coral in most of my Aquariums. It usually brings the Ph to around 7.4.

Great video. You did a good job👍🏻 I have a question, will the lesion heal into a scar that may lead to a colorless spot? Will the scar eventually fade away?

[@haikalachsan]

Doc, i want to know what is the ingridients of your powder that you used to bandage after you give the antibiotic and what is the function spesificly? Thank you

[@MyTinyBalcony]

I think I saw it for sale on the website.

[@hannahking3258]

Loved the video as always. I love the channel its so imformative and different as u dont see many fish vets. Talking of fish vets ohio fish rescue are looking for a vet maybe u could get in contact with them as they rescue many freshwater fish especially the monsters. They are doing amazing things for fish and together i think you would b amazing. Love from london england

Wonderful recovery Dr. Loh. I have a sick goldfish that has developed black spotting pretty much all over now. Started with two small spots about a month ago. How can I help her? If you can respond with an email or pm, I can send photos. Thanks for all you do. ♥️♥️♥️

Very informative Doc...thanks :)

[@kurtschnepf9452]

Excellent work did you recommed to the owner to decrease the number of fish.

[@MonkeyLeggo]

My loach has a dime-sized ulcer on body near his tail. Yesterday I was advised to use melafix. I used it yesterday and today I saw the wound got a little deeper, so I called an aquarium shop and the gentleman recommended metronidazole. Not sure what is best. Any advice is appreciated.

[@wonderwend1]

Fantastic video as always.

[@mikeferguson3251]

My cichlid tank ended up with septicaemia and I’m not sure how to fix it. Any advice I’m afraid of. I’m gonna lose all my fish.

[@professorm4171]

Hey Doc, If you can, do a video on Columnaris.

[@ken33935]

Hello what is the topical antibiotic that you are using? I'm treating a fish with similar issue, thank you.

[@thefishdoctor8746]

You can use betadine diluted 1:10, or sometimes I use diluted injectable antibiotic as a topical treatment, like enrofloxacin or oxytetracycline.

[@lilianabento667]

Awesome video! Can u put the name of the meds that u used, and the dosage? Thanks!

[@wonderwend1]

He mentioned it in the video when he was making it up

[@AliCantate]

The anaesthetic agent was alfaxalone at 6mL/ 30L water (then added 1.5mL later as it was used up) and the antibiotic agent was enrofloxacin 😊

hello doctor how are you. i have one doubt. how to cure black patches for gold fish.

[@thefishdoctor8746]

Consider the distribution of the black patches. Could be normal colour change, or skin irritation from external parasites/trauma. Watch kzbin.info/www/bejne/bZSUeWOZrqeijLs

[@jessicaj.7867]

[@EUAngler]

Hi what powder did u use and what kind medicaments u use to calm the fish?

[@thefishdoctor8746]

Here we used fish bandage (available from shopping.thefishvet.com.au/ ), and alfaxalone as the anaesthetic.

Hi Doctor, My Oscar fish ate Epsom salt whenever mixing on tank and it's not eating(Mealworm & pellets also) properly so no poop. Any stomach issues? Pls assist me dr. From india

[@whydoineedahandleforyoutube]

Love your vids!!! I'm learning a lot and feeling good about fish getting the care they deserve. You seem to always use bare hands when handling fish and aquarium/pond water though -- do you not worry about possible infections?

[@koiworld4496]

Hi Dr my KOI FISH for a teil is damage so what is the reason

[@InquiringMindsKnow]

Please tell me which kh buffer you use and where you get it. I have 2 Koi with red blotchey flesh (1 with small red spot that will become ulcer if cannot stop fast, and the other is worse, large jumbo Koi with bloches spreading and looks like will soon have bad ulcers). I did 2 PP treatments this Spring, but it is still getting worse - HELP SOMEONE? Should I do another PP treatment or try to get antibiotics. Here in CA they passed laws making the antibiotic food illegal....smh

[@InquiringMindsKnow]

Update: I did notice the PH readings were off this am so I re-tested. In 14 years never had a PH problem as I am on well water. This am realized PH crash happened. Did the PP treatements or the Melafix drop the PH? The KH tested 40, PH 6.2, and GH 300 (very hard). Added baking soda, but still need to know if I should do another PP treatment or try to get antibiotics. Salt is about 1.5. Thank you for anyone that knows about this. Before the PP treatments I was loosing a large Koi per year to ulcers.

[@thefishdoctor8746]

For KH, use a combination of sodium bicarbonate (baking soda) and calcium carbonate. If you're in California, book to see my colleague - cafishvet.com/

[@InquiringMindsKnow]

@@thefishdoctor8746 Thank you Doc - so can I use calcium carbonate with Vid D3? And how much per 1000 gallons? ALso, I did a PP treatment, but did not add more after it went brown at 2 hrs in. Will check with your colleague here in ca for antibiotics etx = thank you

[@AZRAEL_FURY]

Hi Dr Rich! My axolotl has a bloated head I'm not sure what to do I feed him frozen blood worms but should I stop fweding him and for how long what other thing can I do? I had him for three years now he is about 6-7 inches long I'm worried. :(

[@thefishdoctor8746]

Check his water temperature is below 22 degrees Celsius. There is poor prognosis once bloating occurs. Keep him cool and seek veterinary care immediately.

In his social media?

[@MyTinyBalcony]

I went to the website on Wednesday evening, posted an enquiry and very quickly got a response, phone consult, and a diagnosis. It is not looking good for my dwarf gourami or the rest of the tank for that matter, but it was money well spent. It wasn't just one fish I was concerned about, but the whole tank.

is "excitatory " a word ? :)

[@h.3531]

My water has pH around 7.6-7.8 from the water supply and has KH of only 2 degrees. Will crushed coral inside the canister filter help raising the KH while not raising pH excessively?

[@allipatton84]

Watch the last few mins of the video. He addresses this exactly.

[@h.3531]

@@allipatton84 Yes I did. But my question is regarding the increment of pH with the use of crushed coral.

[@thefishdoctor8746]

The highest the pH will get with calcium carbonate is around 8.2. If you don't want it to get that high, then have the materials in a removable mesh bag, or combine it with the use of "neutral buffers" available from your aquarium shop.

[@h.3531]

@@thefishdoctor8746 Understood, thanks doctor!

[@kevinw1980]

@the fish doctor how is the pH in RO water drops from 6.8 to below 6 in 4 days? Will the beneficial bacteria die in such low pH environment? And thank you very much for educating us, the hobbyists
