You don't. Wild Bettas do not come from Singapore.
I'm assuming you have access to a fresh water crab because a Betta will not be able to live in salt water. The crab will attempt to catch and eat the slow moving Betta. It is only a matter of time before the Betta is killed.
because they relil on their smell to catch their food or prey and their incredible sight in the dark
Yes, Betta fish can jump. You can teach them to jump by placing a small amount of food on your finger and when your betta fish is ready, it will jump and take the food off your finger! :)
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.
Small crustacea, insect larvae, certain algaes, tiny fry. Basically anything live that it can catch and eat.
A betta is a fish of the species Betta, especially Betta splendens, commonly known as the Siamese fighting fish.
If your Betta is properly housed and fed it will not be constipated. If in doubt, give the fish some live food like brine shrimp, white worms, daphnia, etc. use whatever you can get at your local pet shop or, if you can, go bush and catch your own.
From a female Betta. Then the male Betta fertilizes them when they breed together.
