Shops and/or wholesalers often make up common names. But the latin name is the same everywhere. Seangee's fish are Microdevario kubotai; gold tetras are Hemigrammus rodwayi. The delivery note/invoice should give the latin name.
But even that does not guarantee it to be correct. I found 4 microdevarios in a shop and bought them. That shop did not order fish for customers so I went to another, which did order them. When I went to collect them, the wholesaler had sent chili rasboras (Boraras brigittae) instead, but the invoice gave them as microdevarios. Luckily, the shop agreed they were chili rasboras when they had a proper look at them. I did get the right fish when they re-ordered them.
