It is very difficult to see the markings of these fish from the pictures. Many fish may be able to live with a Betta if there is a large enough tank. Here are some guidelines on how to pick tabkmates for a Betta. No nibblers – if a fish nibbles at a Betta fish they will get bit back!
Bigger fish and colorful fish could be seen to be intimidating – you don’t want to intimidate a fighting fish!
Think of the size of your aquarium – you should always have 5 gallons of personal water space for your betta fish
Many bottom feeders* are fish that can live with bettas
Remember the dietary requirements for both tank mates
Add a few tank ornaments and live plants for any intimidated fish to hide (just incase)
