If I had the tank space and a car I'd come over for a group of them in some months.
Glad it all worked out thus far.
If I had a car and a licence I would have so many more tanks in my room... Ebay Kleinanzeigen is torture for me with all the rare species people breed and sell at absurdly cheap prices just with "no shipping" in description. But it's understandable, I would also not be able to send fish via shipping.
Also there are dwarf cichlid, killifish etc meetings where people exchange and sell extremely rare species they breed. One day, when I have a bunch of free tanks, I must buy some train and bus tickets to visit one (but I guess most likely I should talk and arrange the fish I want to buy beforehand by contacting the breeders, idk how it works exactly).
I personally prefer to see what I buy first. Still, I don't understand the hesitancy to ship fish through the mail/common carrier. I do trade fish with those I know and trust and generally have no problems in this regard. Maybe different countries are different.
I sadly have no places that sell any rare species nearby, pretty much always the same species have been available for years. Buying fish from online stores is a gamble for sure but it's fine more than 50% of the time in my experience. Sometimes they send different species or famished or sick fish tho, or when they write "pair" in the article the fish can be a big male and a sneaker male...
For me shipping is not really possible since the only company I know that can ship live animals, Go!, charges 40 euros minimum for shipping the smallest live animal package I think. I doubt anyone would be wanting to pay that cost to buy some semi rare dwarf cichlids from me lol. Go! charges much less for live fish stores tho, I guess they have some deal or something. It costs only 20-30 euros when I order from a live fish store online, however many fish I order.
Also I don't have any oxygen tanks, idk how long the fish would do well in the bag without pumping oxygen.
