Since changing his tank, my beta seems a lot bigger, is this possible?

Question

I got a beta fish (named Darth Beta) about a week ago. He wasn't the prettiest or biggest of all betas but I liked him anyways. Initially I had him in a 1/2 gal bowl but after reading up on opinions of fish breeders/lovers I upgraded to a 2 gal aquarium with a filter. I've only had him a week but noticed his fins are much longer and he seems overall more vibrant and attractive. Is this in my head? Or can betas actually really significantly change in such a small period of time?

I always heard that the bigger the environment the larger the animal/fish can get but also read this was a myth when it came to fish.

Answer 1

The bigger the tank, the more likely he will grow to his potential size,
the myth is that any fish will grow to the size of the tank, as example a goldie in a fishbowl, that's not true at all, because you will eventually stunt his growth, which means, he will stop growing visually, but his organs won't stop growing and he will sufficate cruely due to that

And no it's not your imagination, they do much better in bigger environments




Hope that helps
Good luck

Answer 2

He was small and not the prettiest when you got him because he wasn't healthy. Now that he's in a 2 gal. aquarium, he has more room to swim in and he's therefore healthier. Keep up the good work and be sure to change %25 of the water every week.

Answer 3

From a 1/2 gal. bowl to a 2 gal. tank..... That would make the betta totally happy, energetic and full of life. That also cure the betta fish which had stuned its growth from the bowl, consider it is a Growth Gap.

Answer 4

I'm sure he has grown some. But the change you're seeing is probably mostly due to being in a much larger environment, which means much less stress, which means much happier fish; so he's bound to seem more vibrant, and beautiful than before.
