We don't normally study fish in vet school, so you would have to go to a specialized doctor in fish... in the whole spain only one university teaches that, so I guess it's difficult to find...

Mirka, it seems as if vets are only truly experienced with cats and dogs, sometimes. I'm very sorry you lost your fish, and there is NOTHING wrong with crying for a lost pet. I have had pet chickens die and I weep for them too. You tried your best and you loved your pet; that's far more than most people do. I have a pet parakeet that has been to the vet already but can't use her legs and can't fly. I may try to make a little sling in the manner of the fellow who helped his fish. We can only try. We do everything we can to help our pets, we love them, and if we have to we help them out of their pain. They give us so much in return.

But you tried didn't you? And you cared & that really counts. My Mum used to say 'Just do your best, that's all you can do, just your best' & I think that's a good adage to live by. I have similar guilt feelings about stuff I should have done or not done for my cats & they still haunt me occasionally. But I was always well intentioned even if it didn't always seem like that. I would never hurt something deliberately unless it was to put an end to its suffering. (Like that horrible crunch when you realise you just trod on a snail & now you have to kill it. I hate that because I love snails.) I'm glad you cared, we should have more people like you in the world so here's a **hug** xx
