Why is My Blue Betta Fish Turning Red

One possible reason your blue betta fish is turning red is a lack of pigmentation in its diet. Another possibility is that the water temperature is too high, causing the fish to become stressed and lose color. If you notice your betta fish turning red, try changing its diet or lowering the water temperature.

Why Did My Blue Betta Turn Red?

One of the most common questions we get here at BettaFish.com is “Why did my blue betta turn red?” There are a few reasons this could happen, and we’ll go over them all in this blog post. First, it’s important to understand that bettas can change color for a variety of reasons.

It could be due to stress, diet, illness, or even just as they mature. So if you notice your betta’s color changing, don’t panic! It doesn’t necessarily mean something is wrong.

However, if your betta was healthy and suddenly turns red, it could be a sign of stress or illness. If this happens, check your tank water quality and make sure there are no sudden changes that could be stressing out your fish (such as a new decoration or filter). If everything looks good there, give your betta a closer inspection for any physical signs of illness (discoloration, fin rot, etc).

If you’re unsure what to look for or how to treat an ill fish, please seek professional help from a qualified aquarium veterinarian. In some cases, Bettas will turn red due to their diet. If you’ve recently changed their food or started feeding them live foods (which are high in carotene), this could cause their color to change somewhat.

It’s nothing to worry about and should correct itself once they adjust to the new diet/food source. Finally, as Bettas age, their colors will often change slightly too. A young Betta might be bright blue with long fins, but as he gets older his fins may shorten and his color might fade slightly.

This is a normal aging process and nothing to be concerned about unless there are other changes happening too (such as rapid weight loss or sudden behavior changes).
