Hello Maurice,
Don’t know if you visited, by coincidence, the aquahortis. There was a very little tank with
One paro specie, deisnerie, if I wrote it right. The tank wasn’t that big and had some leaves, but couldn’t find any fish. Had my thoughts that there weren’t any in there, but it was hard to see. Think the tank wasn’t suitable for paro’s at all. And you are very right to say that display these fish isn’t a very good idea.
