Beta is changing color

Question

ok so i have a beta and its changing colors since i got him. I moved him into a 10 gallon tank and he seems to enjoy the filtered and heated water with the plants and stuff and an aerator. So he is slowly but noticeably growing mettalic blue colors on his upper sides and part of his top fin. It looks really cool but why is it happening? I also bought him blood worms today as a treat and he really liked those.

Answer 1

If he's turning a more vibrant color, that's not bad at all. And yes, mosquito larvae can also be called bloodworms, not to worry.

Answer 2

sorry not sure about the colour change but

bloodworms are another name for mosquito larvae so thats fine

do not touch the blood worms as it is very likely you are allergic to them

use gloves or tweezers and wash your hands afterwards  

Answer 3

i love how female bettas change color. I have a sorority of female bettas, where I have a herd of them all living in a planted ten gallon tank, and it's interesting to watch them change color based on their mood.

Striped horizontally usually means that a female betta is feeling aggressive and dominant or stressed out and scared, and trying to bluff that she's dominant.

Pure color is just a female betta's default mode. If you have a single female in a ten gallon tank, that's how she'll look, all solid color, just chillaxing in the tank. I have one girl who is a very dark purple when she's by herself, but she changes to blue sometimes when she's flaring for a male. It's interesting.

Vertical striped mean that the girl is trying to look attractive to a guy. She has verticals when she is preening for a male. She also sticks her white ovipositor dot out for a guy to know that she's a girl, and interested.

A betta will dip her head down when she is saying that she is submissive to another betta. It's interesting to see them all interact, how one betta will flare at another and get a variety of responses from the other betta. If the betta who is flared at flares back, then she is challenging the first betta's authority. If she dips her head, then she is saying she's submissive. If they circle one another for a few minutes, taking turns flaring, then they're checking each other out.

Female bettas rock :) Their colors change based on their mood, and if you watch yours very carefully, you'll figure out what each shade means

Answer 4

If it is changing color maybe it is growing bigger.

Answer 5

I think the fact that he is changing colors in this case is wonderful. I don't know what you had him in before but he was probably duller before because he wasn't healthy or happy. You will probably notice a lot of changes right now with your betta such as increase in activity, and temperment but these will/should all be good changes!

Just out of curiousity do have anything else in the tank with him?

Edit: I was just wondering because I also have my betta in a 10 gallon aquarium with an African Dwarf Frog, a snail and some tetras...and these make wonderful tank mates for your betta if you are interested in having some.

Answer 6

oh hes fine(:

bettas have a tendancy to do that, im not sure what causes the pigments in the scales to do it, but ive seen that often with my bettas

Answer 7

That what happens when they grow old. Their color will start to fade....

Answer 8

Him turning colors is actually a good thing. I've heard from other another owner that when she took a betta from bad water conditions at a Walmart (it was a dull gray) and when she put it in her tank he turned a wonderful blue with yellow. If it's bright vibrant colors it's just probably him showing he loves his new habitat. Also blood worms are a very good thing to give them since they are frozen that keeps the good nutrients in and kills any bad bacteria. I only give them to my betta and other fish once a week as a "treat" so keep up the good work!
