gge once posted an image on the Mineral Fish topic on Scratch. This method will describe how to make fish bitmaps just like it was shown in the image.
 * Step 1: Get the texture image you want to edit. This is necessary for every Fish bitmap that is based on a texture. You can get the texture from Minecraft's files, or if you don't have Minecraft, you can find the texture online. Please note that some textures that are available online are too big and you may need to scale them down a little.
 * Step 2: Open the texture in an editing program like paint.net or Photoshop.
 * Step 3: Rotate and move the image until you're happy with it.
 * Step 4: Add an eye and a mouth. You can add it to the left side or to the right side of the texture, but please don't add it on the top or bottom of the texture.
 * Step 5: Draw an outline on top of the fish. This will be the top fin for the fish.
 * Step 6: Select a part of the texture and copy it into the outline you draw in step 5. You can also add a pixel on your own if the selection isn't big enough.
 * Step 7: Draw an outline in the back of the fish. This will be the back fin for the fish, and then do the same as in Step 6, but with a bigger selection.
 * Step 8: Draw an outline in the middle of the fish. This will be the middle fin. After you made the outline, adjust the pixels in the outline until you're happy with it.
