Make comparisons fair
Photograph from the same side of the aquarium and use similar room and tank lighting. A different white balance can make shrimp appear more or less saturated.
Include a note with the date and any recent maintenance. A picture without context can be misleading when reviewing a later change.
Avoid stressing the animals
Do not tap the glass, rearrange plants, or repeatedly chase a shrimp into view. Capture the colony during its normal activity.
Use a tripod or rest the camera against a stable surface if movement blurs the image. Avoid long bursts of bright light.
Keep evidence honest
Save original images and label edits or crops. Do not recolor a shrimp photo when using it to compare a line or track a possible health change.
Photos can document appearance but cannot show water parameters or prove lineage. Pair them with measurements and observations.
Use these as general hobby references. Test your aquarium and confirm product guidance before making changes.
