How to Draw Fish: Tutorials, Techniques, and Ideas

Learning how to draw fish is a useful way to practice gesture, shape, pattern, and movement. Fish can look simple at first, but their bodies are constantly curving, turning, and changing direction in the water. Their fins can be transparent or sharply structured, while their scales and markings range from subtle to extremely graphic.

I prefer to draw fish through observation rather than beginning with a standard oval and attaching fins to it. A betta, shark, goldfish, and angelfish do not share the same proportions or movement. Looking at the actual species keeps the drawing specific and gives it more life.

This page is the main hub for my fish drawing tutorials. It introduces the basic process and connects you to more focused guides about fish scales, freshwater fish, tropical fish, sharks, seahorses, and other aquatic animals. It is also part of my larger animal drawing library.

Start with the direction and curve of the body.
Compare the head, body, tail, and fins before adding detail.
Use fins to reinforce movement and balance.
Establish light and shadow before drawing scales.
Study the actual species instead of relying on a generic fish shape.

How to Draw Fish with Shape and Movement

A fish drawing usually feels convincing when the gesture and body structure are working, even if the surface remains loose. Before drawing the outline, look for the main curve running from the head through the body and into the tail. A swimming fish may follow a long arc or an S-shaped rhythm rather than a straight horizontal line.

Then look at how the mass is distributed around that curve. Some fish are long and narrow, some are deep and compressed, and others have large heads that taper quickly toward the tail. This relationship is more important than adding every fin ray or scale.

If you want a complete sequence for one drawing, begin with my how to draw a fish step by step tutorial. The overview below explains the decisions that apply across different species.

1. Choose a Useful Reference

Choose a photograph with a clear body shape, visible fins, and enough light to show volume. A side view is usually easiest for a first attempt. Aquarium photographs and paused video frames can work well, especially when the fish is turning or swimming rather than floating completely straight.

2. Find the Gesture

Draw one loose line through the center of the body and into the tail. This gives the drawing its direction. Build everything else around it. My guide to drawing movement explains how gesture can keep an observed drawing from becoming stiff.

3. Block In the Main Body

Mark the height and length of the fish, then establish the largest body mass around the gesture line. Pay attention to where the head ends, where the tail begins, and whether the back and belly curve in similar or opposing directions.

4. Place the Fins

Compare the dorsal, tail, pectoral, pelvic, and anal fins with the body. Their placement, size, and angle help identify the species. Think of each fin as a flexible form moving through water, not a flat triangle attached to the outline.

5. Add Light, Pattern, and Selected Details

Establish the largest shadow and color shapes before drawing scales or fin rays. Add the eye, mouth, gill cover, markings, and a few areas of texture only after the body feels solid. The drawing does not need equal detail everywhere. Additional fundamentals are collected in my drawing techniques hub.

Drawing Fish Fins and Scales

Fins often create much of a fish’s character. A betta has long, flowing fins, while a shark’s fins are heavier and more structural. Use lines that follow the direction of the fin and allow the outer edge to remain light or incomplete when it is thin and transparent.

Scales should wrap around the body rather than sit on top as a flat pattern. Draw the body, lighting, and major markings first. Then place a few rows or groups of scales where they help explain the form. My guide to drawing fish scales covers the pattern more closely.

You rarely need to draw every scale. A few sharper marks near the focal point, followed by softer or incomplete texture elsewhere, usually creates a more convincing result.

An Easy Fish Drawing Exercise

Choose a fish shown clearly from the side and make four small drawings:

Draw the silhouette in one minute.
Draw only the gesture, body mass, and tail in three minutes.
Add the major fins and shadow shapes in five minutes.
Make a ten-minute version with a few markings and scales.

Repeating the same subject helps you notice its proportions without placing too much pressure on one finished drawing. Try the exercise again with a fish that has a completely different body shape.

Fish Drawing Tutorials by Subject

Freshwater and Aquarium Fish

Aquarium fish are useful because you can observe them repeatedly and compare several views. Bettas are good for flowing fins and gesture, while goldfish offer rounded forms and translucent tails. Koi provide strong markings that wrap around a large body.

Ocean and Tropical Fish

Ocean fish introduce streamlined bodies, sharper fins, strong patterns, and more dramatic movement. Clownfish and tropical fish are useful for studying markings, while sharks show how much form can be communicated without visible scales or elaborate color.

For sharks, rays, whales, dolphins, sea turtles, and other marine subjects, continue to the broader sea animal drawing hub.

Drawing Fish from Photographs and Life

Fish rarely hold still, so photographs and paused video are practical references. Look for images that show real light, a clear silhouette, and visible fin placement. Avoid heavily edited photographs that flatten the form or hide the body beneath reflections.

If you can observe fish in an aquarium or pond, make several small gesture drawings instead of trying to finish one pose. Start a new sketch when the fish turns. Those quick studies will help you understand movement in a way that a single photograph cannot.

Materials for Drawing Fish

A pencil or ballpoint pen and a sketchbook are enough for most practice. Pencil is useful for broad shadows and gradual corrections. Pen encourages fluid lines and makes repeated attempts feel less precious.

Colored pencil works well for controlled patterns and layered color. Watercolor is useful for transparent fins, soft edges, and underwater atmosphere. Browse my guides to drawing supplies, colored pencils, and watercolor for more material-specific help.

Fish Drawing Ideas and Exercises

Fill a page with fish silhouettes from different species.
Draw one fish turning through three different positions.
Compare the fins of a betta, shark, goldfish, and angelfish.
Make a study using only light and shadow, without scales.
Draw the same fish in pencil, pen, and watercolor.
Combine a fish with plants, rocks, coral, or its wider habitat.

Common Fish Drawing Mistakes

Beginning with a generic oval: Compare the actual height, length, and taper of the species.
Keeping the body completely straight: Use gesture to show swimming, turning, or tension.
Attaching fins as flat triangles: Consider how each fin bends and moves through the water.
Drawing every scale: Establish form and lighting first, then use selected texture.
Using one hard outline: Break and soften edges where fins are transparent or the body turns away.

Fish Drawing Questions

What Is the Easiest Fish to Draw?

A fish shown clearly from the side is usually easiest. Goldfish, bettas, clownfish, and angelfish have recognizable silhouettes and visible fins. Choose a clear reference rather than worrying too much about finding one perfect beginner species.

How Do I Make a Fish Drawing Look Realistic?

Concentrate on the body volume, fin placement, lighting, and species-specific proportions before adding scales. Realism comes more from those relationships than from the number of details.

Do I Need to Draw Every Fish Scale?

No. Suggest the scale pattern in selected areas and let it become softer as the body turns or moves away from the focal point. Drawing every scale at equal strength usually flattens the fish.

Final Thoughts

To draw fish with more life, begin with the movement running through the body. Build the major form around that gesture, place the fins carefully, and save scales and markings for the end.

Choose one species and draw it several times rather than trying to perfect the first attempt. Repetition will teach you more about its proportions, fins, and movement than adding extra detail to a single stiff drawing.
