URGENT - Medication sensitivities in AUL (Aussie Lungs)

Have been on holiday for 3 weeks, returned a week ago and have been doing only quick checks and feeds on my large native tank. Finally sat down today to do a waterchange and tidy up on the tank and realised that in my absence I've had a massive infestation of bloody FISH LICE.

Wonderful...

Normally I'd just hit the tank with a dose of ivermectin, and another in a week, but I have zero information regarding medication sensitivities and tolerances with AUL's. Not many people tank about them online and even less (none?) talk about suitable treatments. Because of their prehistoric nature and the fact that other natives (scleropages) can be quite sensitive I want to be 100% sure before anything touches the tank.

Infestation was brought in by my stupid choice to place some native wild caught novahollandae (sp?) mussels into the tank. They'll be removed in the morning and treatment started as soon as I can work out what to treat with and dosage rates.

Any help would be appreciated, thank you!

Entire tank is infested, need to treat all fish.

Sorry, that being said, yes I have alternate tanks available to quarantine, but in this case the entire tank (500 litres and 200 litre sump) need to be treated.

Stock in tank:
2 x AUL
1 x large 7-spot archer
1 x Snakehead gudgeon
2 x Australian Bass

Definitely an option but what I need info on more than anything is whether ivermectin can even be used safely with them at all. I'm not even willing to go 1/2 dose without being sure.

Thanks so much! I will PM him now.

I'm hoping in the end I can get this sorted and I might start a thread for people to share any information about their experiences keeping lungfish so I can put together a website resource.

I've also now emailed London Zoo (because they have lungfish) requesting any information on doseage rates and medications suitable for lungfish.

Called Currumbin Sanctuary and their vets there have never had to use ivermec, so no information but he felt that it would be fine. (Still doesn't make me confident enough)

About to call Underwater world on the Coast and then the local exotics vet. Someone's gotta know. =) At this point it's likely ivermec will be used but I'd like to feel more confident and touch base with people that have first hand experience or research papers on hand.
