Step 6: Draw a similar shape below the betta's body as a guide for the anal fin. These guides will determine the size of the fish's fins later, so you can make yours bigger or smaller if you'd like.

Step 7: Draw a long curved line that connects the two previous shapes as a guide for the betta fish's tail or caudal fin.

That's it for the initial sketch! From this point on, press harder with your pencil to get a more defined sketch.

Step 8: Draw the betta's eye as a circle inside the arc near the middle. Add another circle inside and shade it in for the pupil. Add a few curved lines around the eye for extra detail.

Step 9: Draw the betta's mouth a the tip of the arc on the left side. Use a series of short curved lines to create the top lip within the shape of the arc. Add another short curved line under the top lip for the bottom lip.
