it fat on the left side Try feeding her a pickle. :P Better yet, visit the number one beta site on the web... http://bettatalk.com/ Enjoy!
The male of the species has brighter colours and is a much larger fish than the female

Well, if you mean a Siamese fighting fish (betta splendens) the male are always bigger than the females, and usually the males are more colorful. The males have large tails, as the femaleshave small tails and dorsal fins.
No, I wouldn't recommend it. Bettas can be very aggressive, hence the name Siamese fighting fish.
A marine fungus called "Ick" by professional tank cleaners. It's lethal if not treated. Call the fish store nearby, tell them about this, and lay out the surprisingly realilstic amount of green to get the medications. Then fix this. While not 100%, you shuld have a good chance of saving the fish.
Danios are egg layers and can not get pregnant.
You wouldn't ever be able to tell this, because carp fish do not get pregnant. Pregnancy implies carrying the young internally, which carp do not do.
If your fish is a fighting fish it will be still for most of the day and probably attack another fish who wanders into his "territory". Fighting fish often come in bright colours like red or blue. But some fish are just naturally aggressive and hurt or kill your other fish! {trust me I've experienced this } It's very important to know the difference between a aggressive fish and a fighting fish. If you still can't tell talk to your local pet store or talk to an expert.
look at the color... if its bright and colorful its a male. if its colorless its a female.
Goldfish of any type are all egg laying fish which means that they do not get pregnant
With a guppy you need to look at the gravid spot. This is a dark spot in the fish's belly. A large gravid spot indicates the fish is likely to be pregnant. You can tell how pregnant the fish is by how large the spot is. Sorry I have no experience with other species.
Orandas, or any other type of goldfish are egg laying fish, so they do not get pregnant
