I think you are confusing "betta" with "beta". Beta radiation is a form of energy that isn't very good for you, similar to x-rays in simple terms. They can be used to treat some forms of cancer but are generally considered a bad thing to be around. Don't worry - Siamese fighting fish do not emit beta rays, it's just a similar name.
all three are very different. Alptha is very small particles that are radioactive like dust to sand grains size. Betta are slightly bigger and give off radiation. betta is whats in x ray machines and basically anything with a radiation symbol on it. gamma is just radiations and is not a solid object and is what comes off of alpha and betta. there is another called Neutron but this is only present after a nuclear bomb and cannot be detected from Alpha, Betta or gamma.
beta is not a word, it is a greek letter at the end of the alphabet. In chemistry, it is a type of radiation, and in math it is a varible.
There are half moon betta, delta betta, round tail betta, long tailed betta, crown tailed betta, king betta, and others I don't know of yet.
A betta is a fish of the species Betta, especially Betta splendens, commonly known as the Siamese fighting fish.
From a female Betta. Then the male Betta fertilizes them when they breed together.
a wild betta
A betta can eat any betta food regardless of the manufacturer; they typically market it as Betta Bites.
no because male betta's are really aggressive to other betta's which plakats are male's. but female betta's can stay with other females. don't try to, one of your betta's are going to end up dead.
