Please find attached a picture of my clown. So as you can see his tail fin seems a bit damaged.

how do I find out what's causing it? is it dangerous? and how do i solve it?

That sort of look is almost always from an injury. Either another fish, or from a net when it was caught up and moved to a new tank, etc. True fin rot, starting with no previous mechanical damage is very rare, and looks smoother along the margin.

In any event, the treatment would be a broad spectrum gram negative antibiotic in a treatment tank, along with isolating the fish from any possible cause of the damage.

Would you consider watching it in an observation tank first - as compared to treating immediately? I thought as others that it was mostly injury.

For all of our knowledge - and I think I know the answer but I'm not sure. Are the levels that we eventually get when dosing antibiotics in our tanks (in the water) - the same levels that are attained in the human body - i.e. can you use the M.I.C. (minimum inhibitory concentration) from the tables to try to determine whether drug x is likely to work? Second - do you of any topical treatments that can be used (other than antibiotics) for injuries such as this - i.e. do you think stress coat, etc help?)

IMO - if you are going to set the fish up in a new tank (as opposed to just using a tank divider) you might want to treat with an antibiotic just to play it safe. In this case, if the OP is correct and there was no mechanical damage, then for sure you would want to use an antibiotic.

I don't use topical medications, they rinse off too fast, and the extra handling usually just makes the issue worse.

I also do not rely on any of the "bandages in a bottle" for anything more than dechlorinators. The idea that they will preferentially seek and and coat injured areas is false, they coat the whole fish, including the gills. People tend to use these as an easy primary medication and that is a mistake.

Hmm, i checked again now and it seems the tail is more damaged than 3 days ago ( when i made the first picture). The stange thing is that its only his tail but the rest of the fins looks normal
The only other fish in the tank is the smaller clown and he is really not aggresive, so i can not believe that it would be the small clown nipping, the smaller clown always seems to be a bit afraid of this clown

I dont now if you saw @Jay Hemdal 's post just above - he suggested - a QT and antibiotic treatment. I agree with that especially I worse (from this picture I don't see it exactly) -

To be sure, Set up your phone on video mode. Drop some food and walk away for at least 45 min mins (you Must walk away) and come back and review video. Often aggressors will get aggressive at feeding time trying to dominate the food. You may then see whats going on here

Hmm yes, but the bigger clown is always chasing the small one when i drop food. Then the small one waits and its showing respect to the dominate one, the small one wait for his turn. But the damaged fin fish is the big clown, thats the strange..

Bigger being female is often the aggressor but smaller (male at times) will at times defend itself. Reason males are often smaller is that females steal all the food. Viddeo will detail what is happening in your absence.

Those are indeed getting worse. If that doesn't stop, it will eventually consume the entire tail, so I think my previous advice would be what you should do now:

"the treatment would be a broad spectrum gram negative antibiotic in a treatment tank, along with isolating the fish from any possible cause of the damage."

That said, it looks like this fish also has white stringy feces. That can be from a number of causes, some more of a problem than others.
Is the fish still eating well?

Hi Jay, sorry but I really dont know anything about this antibiotic treatment, is there any topic here where this is explained step by step? ( the hospital tank is already set up some time ago, and it is free to use)

and the white poop can be of the mysys. I feed them now 3 times a day and they are both always eager to eat a lot. No other problems/stressfull behaviour.

Antibiotic treatments for marine fish generally revolve around using a broad spectrum, gram negative antibiotic. I'm not sure what you might have available to you in Spain. I like to use Neoplex. You could also use Maracyn 1 and Maracyn 2 in conjunction.

If you have other types of antibiotics, I can look them up for you as far as dose and how well they might work.

I checked and I see I could get Neoplex from seachem imported from Amazon US ( takes 8 days for delivery). This should be the right one? And how long will take this treatment in general? And how do I know after the DT is free of any bacteria that causes the tail damage?

Hi Jay, do you think Rally Pro will be a good alternative to try first in the display tank? I read it can cure also fin damage.
