Types of Rare Betta Fish
The rarest type of Betta that I could find is the so-called fantail variety. This fish has two caudal fins that are side by side but fused at a small point at the top, making it look similar to a fantail goldfish. This variety is so rare that you can't really find any information on them or anywhere to buy them.4 Mar 2021.
