The MPI-ABTRT (Approved Biosecurity Treatments for Risk Goods) has been amended effective 24 September 2025.

Treatment Requirement: Approved Biosecurity Treatments [PDF, 1.2 MB]

The main changes are the addition of a new treatment of ballast water and the replacement of a chemical for the treatment of snails on nursery stock.

Other minor administrative changes to improve clarity are also implemented, noting that some information will have moved within the document.

Finding treatment options and providers

I tested my water about 7 days ago an everything was perfect, tested again last night and my ammonia had bounced up. 

I moved him into a hospital tank within a couple hours an treated with tonic.

This morning when I checked him it was way worse, the end of his body was abit patchy and fins more deteriorated. 

My locals said that there's nothing more I can do at the moment.

I'm very worried he won't make it through the night, he's starting to struggle.

Any advice is much appreciated.

I was out shopping tonight and saw some epsom salt at the supermarket so bought some.

What's the difference between the two and do either affect pH ?

There is nothing seems to be on my datnoid body. But he seems itchy.

could you please advice a suitable medicine

About a year ago we bought a 240 litre tank that came with a variety of fish.   We lost a couple of the older fish at the end of last year.   Early this year we purchased two Pearl Gouramis from a reputable supply.     About 5 weeks ago, one of the Pearls developed a lump on its side that then turned into an ulcer looking wound.   It died a couple of days later.   Our second Pearl then started to not eat as much, not be as active and staying at the top of the water.   We did a water change and planted some new plants and following that the Pearl changed colour.   We presumed due to stress.    It is only the front half of the Pearl that has changed colour.   It is now about 10 days since it changed colour and it is still alive but still not eating and staying at the top of the water level.   Today, we are concerned that our big Red Rainbow is sick as well as it is not as active, is not eating like normal and has turned a very dark colour.

I tried researching the unusual Pearl colour change and could only find one reference to it and it indicated that it may be iridovirus.

Our water tests are all ok.

I have attached two photos of the Pearl with the lump and two photos of the current Pearl with the colour change.

Thanks in advance for your help.

Still don't know what caused it, no new fish had been introduced and there was no nitrogen buildup. One of my fish must've been incubating it for some time. Their were no signs of illness or lethargy, no ulcers, so we were checking for heater malfunctions, pH fluctuations, pretty much everything else. It was only when one of the larger fish got a crooked spine we worked it out, diagnosis was confirmed by professional biopsy.

There's only really cleanup left to do now. Have a fish-less display and hospital tank full of Mycobacterium water. Does anyone know best way to sterilize the tank, and safely dispose of substrate and plants? It's going to be important not to release it into the environment, there is a nearby frog breeding area and would like to protect it from introduced infections.

Goldie is about 18cm and lives in a 65L tank alone, I am unsure of her age. She was rescued from a pond which had dried up a few years ago when she was much smaller. I am trying to obtain a sample of water to test, currently the owner is doing approx 1/4 water changes every few days. There is a filter which has not had much maintenance in some time. Goldie is active and has a big appetite but gets very stressed with disruption to the tank.

I was sent the following photos of the growth, but I am not sure what advise to give her. It started with a swollen gill plate. The tail pic shows a slight red streak which may or may not be related.

I assume this could be caused by water quality or by an infection, can anyone enlighten me? Is this reversible or improvable? What is it?

Thanks very much for your time.

Me with yet again another fish issue. 
 

One of my X-Ray tetras has white spots on both its eyes and is acting a little odd. 
https://ibb.co/bNQzsQ6

I know that ich is white spots but usually that covers the body or starts on the gills right? From my post history you can see I lost another X-Ray a little while ago to a different illness, but it did not have white spots on its eyes. 

But while I’m here I’d like some more general advice: this is about the third or so illness in a few months and I’m not sure what’s going on. I do 30% water changes every week, I vacuum the gravel every few weeks, I have a high quality diet etc, I test the water regularly and have a planted tank. Is there anything I’m doing wrong? 

Yesterday I had to put a gold barb down because it had been manically swimming at the top of the tank for a month or so without eating, I can upload video if anyone is interested. It was not swim bladder, seemed to be something else? It feels like my fish get illnesses that don’t spread, all with different symptoms, so I’m a little stumped. 

I have run a praziquantel cycle and then a week after it finished and I did several water changes I ran a week course of Melafix. 
 

Any advice would be great because losing fish regularly is becoming quite upsetting.

Sorry for the long post ? 

Woke up this morning and my X-Ray Tetra has issues swimming and is spinning around as can be seen in the below video:

Checked the water and nothing out of the ordinary: 0 Ammonia, 20ppm Nitrate, 0 Nitrite, 7.4 pH. We've had these X-Rays for about 14 months so they're not new. 

Only recent change to the tank has been adding 3 baby Gold Barbs from Hollywood Fish Farm about 2 weeks ago. 

I have Melafix on hand but I've never used it before and unsure if this is the right treatment. Any help would be appreciated.

I’ve fed it peas the last two days but I was wondering if anybody has experienced this or if there’s anything else I could do to help it apart from feeding the peas? 

Thanks in advance. I can post videos if anyone needs a look.

Long time no visit, so long in fact I'd forgotten my login details. ?

Have been out of the fish keeping for about five years, but just got back into it last year.

I have a neon rainbowfish that I've just noticed has an odd discolouration at the base of its tail, its on both sides.  To me it sort of looks like a dark pimple?  I'm guessing maybe a parasite or worm?   Any ideas?  I've attached the best photo I could get.

Cheers

Has anyone seen this get better by itself? Would tonic salt help at all? I'm a bit worried his days may be up soon.

I have a 57l tank (fluval flex) with two neon tetras, five (now four) Rosie barbs (3 male, 2 female) and two Mystery Snails. I suspect the neons think they are rosy barbs. We got the Rosies about five or six weeks ago. They are our newest addition. Before they arrived, we lost a few neons to "loopiness" (erratic swimming and the inability to stay upright, then they die). But the remaining few cheered up considerably when the Rosy Barbs arrived and seem healthier than ever.

One of the male Rosies started looking very skinny and his eyes were bulging. He has since died. Another male rosy is also looking quite pale and thin, but not as bad as the first (yet). The third male rosy looks spectacular. Very rosy. Not skinny at all. The females are suspicious round and I wonder if they are carrying eggs. 

Is this normal for spawning time or is it stress or a disease of some kind?

How can I tell?

We don't have a quarantine tank, unfortunately.

Looks quite puffy, flakey. Not sure if it's the scales or what! Can't find anything on the internet.

About 3 days ago I noticed my black neon had a prolapse and had a protrusion under her vent. I used some Methylene blue and Epsom salt to help, after 2 days she expelled a few eggs and a day after she has a triangle-shaped hole under her vent. She doesn't appear to be stressed but not sure if I should euthanize her. I have also used Stress Guard from Seachem as an antiseptic.

All the fish are usually friendly, the rasboras, black neon and neon tetras are always schooling together, the Dalmatian mollies are very friendly and show no signs of aggression towards other fish. The snails, corys and loach mind their own business at the bottom and are very peaceful.

We also have live plants, will they be able to tolorate this stuff?

German Blue Ram - Bulging right eye and white around it. Left eye looks normal. He also has a white mark on his right flank, was slightly raised/lumpy but appears to be healing after a week or so (still the same size but is flat, no longer lumpy). Also small white spots on right pectoral fin. These spots have shown up previously (weeks ago), exact same place, and were treated successfully with Melafix at the time. Had put this down to a scrape/injury as he can be very skittish though now they’re back along with added issues above something more serious may be going on? Treating tank with Melafix and Pimafix currently. 

Tank size: 120L / 30g tall, planted, driftwood rocks etc

Tank mates: 5x Harlequin Rasboras, 5x Glowlight Tetras, 3x Otocinclus (soon to be 2 though, one looks like he’s on his way out but due to ignoring algae/food not showing any of the symptoms of the GBR)

Parameters: PH 7, Ammo 0, Nitrite 0, Nitrate 5

Inherited established tank about 6 months ago, was running for about 12 months prior with previous owner. GBR introduced around 4 months ago (there was a second, female, which this remaining male sadly bullied to death)

Have also lost other Otocinclus over time in this tank, though parameters have appeared stable/safe throughout (weekly testing and weekly water change around 25%). Keen first and foremost to make sure I’m doing everything I can for the GBR but any advice on keeping Oto’s alive for the long haul appreciated also!

Thank you

PS: How do you attach video to posts here?

We've googled and read about gas bubble disease, how do we know if these are gas or fluid-filled?

We've tested the water and that seems fine. We have another Hillstream Loach and he's fine and 6 glowlight tetras who seem fine.

We have an Aqua One EcoStyle 61 tank.

Any help appreciated. Thanks.

 I noticed the other day my two GBA adults have white patches. It doesn’t seem to worry them and neither have changed their behaviour. So I guess just unsightly, does anyone know what it could be and what could be a possible cure? 

Certainly something outside of my experience currently.

I have tried treating for the usual suspects fungi and bacteria and there’s been no visible change. What else is there that could produce a blotch type result?

Let me know your thoughts as I’m stumped.

Cheers

I'd appreciate your advise!
