Fish from the wild to the aquarium

[SLS_23]

Hi, I would like to ask what needs to be done to be able to put a fish from the wild into an aquarium. Of course, I count on a long quarantine, but is it good to do something else? Treat the fish and remove the parasites with some kind of preparation? I wouldn't want to endanger the fish I already have in the aquarium.

Yes definitely quarantine and do observation of the fish daily for unusual behavior and parasites.

Could someone recommend me some anti-parasite medicine that can be found in Europe?

Totally agree.
Because all the fish I get are caught wild, I really study the actions and outward appearance carefully for any anomalies, like the Lernaea on the caudal of the tetra below.


And with an adult parasite (above), medications are sometimes only partially effective, so physical removal may be needed.

If its something simple like 1 ick spot, treating it in the Q. Tank may be all that is needed.
But be sure the quarantine process is long enough to allow the disease or pest to become obvious.

I usually QT as an individual, or if they come in as a group together at least 3 months, to allow this.Many diseases, that may incubate for long periods before becoming apparent.
Its so much easier and less expensive to treat in small volume of a QT tank than to have to treat the main tank.
And especially taking into account the damage and stress many meds can do to plants and biomedia.

Thanks everyone for the replies. I would like to put a European eel in the aquarium.

If its going to be the only fish in tank, QT is not quite as important, unless you need to treat a large volume of water, then meds become more expensive.
If something easy like Ick, 3 lbs of rock salt (NaCl) per 100 gallons is adequate.
Qt comes most into play if there already important, hard to get other fish in the tank it will live in.

The tank is full of cichlids. I have seen european eels from river kept with cichlids several times here. Local ZOO have them too with Oscars.
