balloon belly fish

What is the deal about balloon belly fish. I mean do they have some genetic problem or something. so far I've seen mollys, rams, and pearl gouramis. How did these fish get to have such big bellys.

 

Genetic mutations made by man. Lots of people are against them. I had 2 balloon mollies before I found out.

 

I thought that was just for mollys. Then I saw rams then when I went to san diego I saw a pearl gourami. That sucks people would do that. I heard that's what they do to neon tetras and glow fish. they inject them with stuff to make them look the way they do.

 

Neon tetras? Glofish?

Respectfully - Neither of those species are dyed. The Glofish is a genetically altered zebra danio - there are plenty of threads here on Fishlore about Glofish.

To the best of my knowledge, Neon Tetras are all natural, and are natives of South America. (Paracheirodon innesi)

Glassfish on the other hand, are dyed by injection.

 

I didn't know glassfish were dyed. Thanks for the info. I almost bought a colored set in the past. I think genetically altered fish are imperfect and prone to deformity and disease. That's why I don't buy them. Selective breeding on the other hand are a different story. I think it's still natural evolution but with a helping hand from humans. A perfect example would be dogs. Dogs did not originate from the wild. It's a process of hundreds if not thousands of selective breeding that takes decades.
