If you can get a female of the same type as the male you have, that is best, but any female Betta will spawn with any male Betta provided they have the correct conditions and are both ready to breed.
If you are talking about reproduction then that would depend upon the genetics of the breeding pair. A none crowned fish (male or female) may carry crowned genes and throw some crowned young.
Clown fish are not schooling fish; initially they are all male, and at some point they will pair off and one will become female, they then spend their entire lives in and around their anemone.
YES...I HAD A PAIR OF REDSWORDTAILS AND A PAIR OF GUPPIES. MY FEMALE SWORDTAIL DIED...THEN MY MALE GUPPY DIED...LEAVING ONLY MY TWO FISH. IT WASN'T LONG UNTIL MY GUPPY HAD BABIES...AND THEY WERE RED, BUT I DIDN'T GET THEM SEPERATED IN TIME...THEY WERE EATEN. I DIDN'T TRY AFTER THAT TO BREED THEM. THEY SOON DIED AND I DIDN'T GET MORE FISH.

With convict fish, the male will usually be larger than the female of the pair. As they pair, they will keep close company....and THEN...they will choose a territory...often a corner of the tank, or perhaps an attractive rock...and begin to defend it against Intruders. Defending territory against Intruders is an important step in the pair-bonding of convicts, as for most cichlids! It is Good for them to have Intruders to Defend against, as it strengthens the bond between the pair.

One word pair that can be used for 'chips' is "fish and chips."
No
by pooping on themA male fish fertilises the eggs After they are released by the female, either by releasing sperm alongside her, as she drops the eggs, or by floating above the batch after the eggs have been dropped, and releasing the sperm into the water above them. There is no real contact between a breeding pair.
