Fish missing fins

[Beastije]

I would do 50% at least 2-3x per week while healing to make sure their water is pristine. Increasing your one weekly water change by 20% is not enough to promote healing in my experience.

Oki, good to know, thanks.
Especially since I have to reduce my filter flow to minimum, otherwise the rasbora would be too tired from the heavy flow, it makes sense to do more frequent water changes than one larger one.

Update, in just 10 days and both the harlequins that had only small nips in the tail are all healed. The third one who was missing almost all the tail is growing it back at a nice pace, it is like half there now. I do normal changes of the 30% every two or three days and feed real well. No fungus or anything, good to know their regenerative abilities are this good

btw the narrower more nipped fish that is not looking as great as the other one has been like that past 4 or so months, I think it is reaching its end and that was why it was more nipped than the other one. The healthier is still missing small piece on the bottom of the fin, didnt notice before, so not 100% yet

it probably has worms and gill flukes.
see section 3 of the following link for treating worms and gill flukes

What to do if your fish has Stringy White Poop.

Fish do a stringy white poop for several reasons. 1) Internal Bacterial Infections causes the fish to stop eating, swell up like a balloon, breath heavily at the surface or near a filter outlet, do stringy white poop, and die within 24-48 hours of showing these symptoms. This cannot normally be...

Not saying that is not a possibility, based on the marking this should be a female so yes, should be larger and not so narrow.
However, so far, no vet I contacted is selling esha products at this moment and I am not comfortable playing with the flubazone directly

You won't buy esha products from a vet, they are from pet shops or online (eBay).

A vet should sell Praziquantel to treat dogs and cats for tapeworm.

A stockfeeder should sell levamisole to treat round/ thread worms in sheep, cattle, pigs and poultry.

Not anymore here, anything that contains praziquantel or levamisole, in esha products, jdk, in pills for deworming, in any form, is vet regulated here. No shop is allowed to sell this medicine anymore, same in Germany btw. Some new EU law that is slowly trickling down (to limit antibiotic overuse I guess).
I am looking into vets that would do microscopic analysis of the worms present in the fish tract, not sure about the price or possibilities but they do that here, which helps narrow with what to treat the tank.
Given the usual approach is to treat everything in waves just in case, which kills bacteria, might kill snails, might kill shrimps, it is not really good idea to just do that and hope for the best.
