BellaOnline Forums Home and Garden Fish Do Bettas Change Colors as They Age????

My blue betta, Elmer, is getting red on the top of his head and on the belly down toward the fin and even on the top part of the fin. When I first got him, he didn't have those long fins that are under the chin and he grew those. They have red on them and white on the very tips. His eyes now have a white crescent shaped stripe above them. This has all happened within a week. I don't know if I like the reddish coloration, but if that's what he's supposed to be, that's fine. He is so pretty anyway.

Just wondering if anyone else has fish that changed colors.

My red fish (Eric) is solid red all over. He is still quite a lot larger than Elmer and is showier than Elmer because his color is so vivid.

Both fishes are so much happier now that they are in 1 1/2 gallon tanks that have a heater and a filter. I still change part of their water every 2 to 3 days and do a complete tank & accessory scrub & water change every month. I change the filter every 2 weeks. They are happy, happy and so am I.

Hi, yep, they do change colors! Would send a photo, please, so we can check? It's just that, red being a common color for many betta fish, it's probably just normal, but on the other hand, red is also the color of inflammation and disease on betta fish as on people and other animals.

Yes, I have a betta fish, who, when I brought him home, was originally blue and then slowly got darker and upon inspection with a flashlight, you could see that he was also turning more and more reddish in the dark red way autumn leaves change colors. He's fine and beautiful - that's just his adult color. He was about 8 months old when I got him - so now that he's about 3 years old - he's got his full, natural colors.

Also, Betta fish can change with the color of the decorations you put in his tank!
