In rare cases, bettas may bite their own caudal fins causing fin loss. Bettas have been selectively bred to illustrate a variety of caudal fin shapes including halfmoon, double tail, delta tail and the common veil tail. One of three unpaired fins.

3. Anal Fin – Used for stabilization while swimming.One of three unpaired fins.

4. Pectoral Fins – Used for turning and propulsion. These paired fins are located just behind operculum.

5. Ventral Fins – Sometimes called pelvic fins, these are used for fine motor skills like sharp turning, ascending and descending in the water column and stopping.These are paired fins.

6. Operculum – The gill covers that protects the fragile gill tissue from injury or damage.

7. Caudal Peduncle – The area at the posterior end of the betta’s body just before the caudal fin begins.

8. Eye – Bettas have very good eyesight and can see in color. They often react to movement outside their tank or their own reflection.

9. Mouth – Bettas have an upturned mouth used positioned to fetch insect larvae and small insects from the water’s surface.
