Bettas like flowy plants, but not ones that are hard and can tear their fins. They also like a place to hide or rest as well, so you can look at some sort of decoration that gives them the opportunity to hide out when they feel like it.
It depends on the type/brand of conditioner, and how much water is the Betta tank can hold.
you can put a betta in a 54 gallon tank
Do not put any sharp angular things in the tank and do not put another type of fish in your betta's tank.
put it in a tank with another male betta
you can put a betta in a 5 gallon tank
Provided the tank is large enough and the catfish is a tropical species there should be no problems.
The eggs will be in the tank and if the dad's in the tank take the mom out.If the dad isn't in the tank take the mom out and put the dad in.
You should not put your Betta fish in the same tank in the first place, most likely the male will kill your other fish. by res do you mean red eared slider?
First make sure if you put tap water in there you put water cleanser in there which can be bought at a pet store. Keep your betta in the bag and float it in the tank for 15 min. then without dumping the bag water in the tank use a net to move your betta to the tank.

No, you should never keep a male and female betta fish together for long time periods. They should only be put in the same tank for breeding purposes and then separated after.
