If the fish have been deformed externally in such a way, what damage has been done internally, what will the long term effects be on keeping such fish and moving them out to people.
Will they be prone to illness - most probably
Will people keeping them as they were so cheap start reaching for the medicine cabinet - most probably
Will many die off through med over dose or have a shortened life span for other reasons most probably.
Will people then say discus are difficult to keep - who knows?
The discus world is full of myths and bs, just like many specialist pets
I am not saying it is right to rear them or right to cull them - that is up to the owner.
Just saying careful thought is needed.
I personally would cull but if in doubt keep until 2" and make a decision then, but the longer you keep the more difficult it becomes
