that's a real shame...but I suppose it happens in all hobbies, I see it in tropical/marine fishkeeping as well...(it shouldn't.... people should read around the subject etc etc, and there are plenty of support networks, courses, books, BBKA, associations etc)
but with some "beekeepers" I've dealt with, and I use the term "beekeepers" litely, they've not followed advice given!
purchase fish, and have no understanding of how to keep them.....other than OATA are now working with Pets at Home/Retailers, and Pets at Home staff are now asking questions, to ensure the welfare of the fish, are well looked after!
(well they should be!).
