Reduction of Dark or Dull Areas
Growth of Clear Margins

As Betta fish experience healing, the transition from unhealthy to healthy coloration can provide valuable insights into their recovery process.

Restoration of Original Color:
Restoration of original color occurs when the fins regain their vibrant hues. Healthy Betta fins are usually bright and colorful. When Betta fish are recovering from ailments like fin rot, their fins often appear discolored. Once healing begins, the original colors start to re-emerge, indicating that the tissue is recovering. Observations from aquarists show that within a few weeks of effective treatment, original colors may return fully, suggesting a healthy healing process.
Development of Faint Red Tint:
Development of a faint red tint signifies new blood vessels forming in the fin tissue. This can occur during the healing process as fresh tissue replaces damaged areas. A study by Björn et al. (2021) in the “Journal of Aquatic Animal Health” highlights the significance of this tint, noting it can indicate improved circulation and healing. Aquarists report that this red tint typically appears around the edges of damaged fins first.
Appearance of Sheen or Glossiness:
Appearance of sheen or glossiness often indicates that the fin’s outer layer is recovering. Healthy fins typically have a shiny surface. When fins begin to heal, an iridescent quality may emerge, signaling new tissue growth and restoration of protective layers. According to Johnson’s 2022 findings in “Fish Veterinary Journal,” this change often occurs after effective treatments such as antifungal or antibacterial medications.
Reduction of Dark or Dull Areas:
Reduction of dark or dull areas signifies the improvement of fin health. Dark spots or dull patches typically appear on damaged fins. As the fins heal, these imperfections diminish or disappear, revealing healthier-looking fins. Observations suggest that the timeframe for this reduction can vary, but it usually becomes noticeable within two to four weeks post-treatment.
Growth of Clear Margins:
Growth of clear margins refers to the development of translucent edges on the fins. This sign indicates that new, healthy fin tissue is growing, pushing back the damaged areas. According to research by Morrow et al. (2019) published in “Aquaculture Research,” this growth reflects the success of treatment and the refurbishment of fin structure. Clear margins often appear before full restoration of color, indicating active healing.

These color changes can serve as strong indicators of a Betta fish’s recovery from fin damage, guiding aquarists in their care and treatment strategies.

How Do the Edges of Betta Fish Fins Appear When They Are Healing?
