Is this a good combination of fish

okay, so heres my suggestion to you. youre tank HAS to be atleast 20 gallons if you are getting that many fish, small or big. next you can NEVERRR put a siamese fighting fish with another! they have to be isolated at all times, unless you want to breed. even after breeding the female siamese fighting fish will kill the male. you must be extremely careful with them. considering you want a male, they are more aggressive with other fish than a female. for being very small, they are one of the most aggressive fish! everything else sounds okay, but i wouldnt get the catfish. even though its a bottom feeder, it doesnt fit in with the other sizes. too big.
