How many discus do I have to buy to make sure I have a pair. Is it like angels?
Reply:
1. You will buy the 2″ baby fish from one breeders, if possible.
2. Choose the fish that are in one brook or same batch.
3. If you buy 10, pick 5 bigger ones and 5 middle size.
4. You will get at least 3 pairs or more, if you are lucky.
5. The bigger ones are normally males.
6. The smaller ones are normally females.
7. If you buy from the pet shop, usually they are from many batches, then you cannot judge them by size.
