Betta Color Change with Water change

[Demeter]

Perfectly normal. Bettas have been bred to the point of many having the marbling gene, meaning they will change color as they age. White/cellophane bettas with a little color on them usually change to an almost solid color.

Looks like some amazing coloring to me.

Thank you!

I’m glad to hear it! I’d read about the marbling gene but I wasn’t sure if that’s what it was since most of the examples I saw looked like they changed pattern rather than changing to a solid color. Thanks for letting me know!!

Ok. New here. I have 2 betta fish. My newer lad is a Halfmoon King. Azazel. He is the largest Betta I've ever seen EVER. IVE SEEN A LOT. And he was the strangest color. He was a pink hue, almost clear like I could see inside him with black blotches and red blotches. Gorgeous. Most beautiful fish I'd ever seen.
Took him home. Gave him a tank and a heater as it was still cold out and water stayed at 42 without.
He decided to live behind the pump and literally lived vertical for a week. Up and down lodged between. Coming to eat and going back where he didn't even have to swim. Only moved closer to the heater. Then we gave him some leaves and diff treat food. Now he's changing there are patches of shiney blues and blacks strangest **** thing I've ever ever seen. I've seen discoloration. My older one was beginning to fade. But him? He's gaining and I'm scared..
Now I also see that my older fish, Gerbaud, who I brought out of a very nasty tank and brought to a clean home has a patch right where the top fin touches his back and it appears to be in the base of the fin itself. I'm using Bettafix for 7days in hopes to help. Please tell me is the color change on Azazel ok and what is this on Gerbaud? God bless!

perhaps he was discolored due to stress at the store and now that hes better hes getting more colorful? im not that experienced on bettas tho haha what are you keeping him in?

It's normal, they often change color due marbling gene. He's stunning!

 

[Broggy]

fish sometimes lose colors if they are sick. what are the water parameters?

Usually when bettas change colour, specifically gain colour, is a really good sign. When we buy bettas they are usually in a very stressed state, so what you initially see is them actually discoloured, and not completely showing off their true brilliant colour! Because you’ve provided Azazel with what i’m assuming is much cleaner water and better conditions than what he was previously in, hes finally showing you that he’s becoming happy and healthy by bringing out his amazing blue colours. So congratulations to you on that.
As for him “lodging”, that’s quite strange. Bettas are known though for being pretty “lazy” at times, do you have a betta leaf bed for him? They are popular and you can find them everywhere because of bettas being known for their “resting” behaviour.
Your older one is fading, which means the opposite of what it means when bettas gain colour. He must be sick or unhealthy, but it may not be your fault! He could’ve caught some sort of illness because his immune system would’ve been very weak in the water he had before you rescued him. I would continue to treat Gerbaud with bettafix until we figure out the real issue with him, but i don’t see any need to treat Azazel.

Totally normal. Bettas have a marbling gene which means over time they will change color. Hope this helps

Sometimes the color change is drastic too! I have one that was all blue and white when I got him. He now has a lot of stunning red in his fins. Went crazy at first thinking it was blood streaking lol.

I cannot count the number of times this has happened to me. Your new betta is happy, he may end up being a bit lazy at times I had tall leafy plants in my tank all the bettas I kept in there loved it. They would literally rest on the top only moving from one hygra to the next it was hilarious. I had one that I don't think he even knew the bottom of the tank existed, he would swim behind the filter and heater if he was cold or chill in the slow-moving currents (I had to make a diverter to reduce the flow) when the mood struck him! Brighter usually means better. The other that is fading can you give more information like your water parameters and what you are observing as well as pictures (assuming he will cooperate) those would all be really helpful to everyone!

He has a 1.5 gal tank he loves. It's got a bit of hiding for him and I put leaves from his native habitat and ecosystem to give his water the appearance of such.

Hi!

He's a beautiful boy!!!

Since he is such a big betta, you might want to upgrade him to a larger tank, when you can. If he is a juvenile, he will be getting larger, and will need more room to swim around and grow.

Small tanks like that require frequent water changes. I would change 50% every other day.

I hope has a long and happy life!!!!

I should probably mention I kept all of my bettas in a fully planted 10-gallon tank with a few bottom-dwellers to clean up his crumbs. The 10 gallons are nice because all the parts are easily replaceable (i.e. when the heater goes bad and just stops working for no reason) in a smaller tank it becomes difficult to impossible to replace equipment if needed. I had a 5 gallon that was really nice, but the filter crapped out. I wasn't able to replace it so I had to figure out how to fix it. it was easy as some of the plants had grown too tall and got sucked into the filter and tangled up on the gears, but still lesson learned.
