Your triops could be growing slowly due to a number of reasons. First of all, perhaps there is not enough food for them. If you have been feeding them as per the directions in your kit (I assume that you are a child using a kit, because you used an adjective in place of an adverb, and placed your question in the "Goldfish" category), this should not be the problem. In that case, check the following:
The water quality. Is it extremely cloudy or odorous, possibly from overfeeding? The build up of wastes in the water could be inhibiting the growth of the triops. Once your triops have reached a decent size (so that you will be able to remove them with a net), perform a 100% water change using either spring water or dechlorinated tap water. If you used plain tap water to begin with, by the way, that could also be hurting your triops' growth.
Next, how much water are you keeping the triops in? Though they need a small amount of water when they are hatchlings, triops can quickly become cramped. They will only reach their full size if given adequate room.
Finally, if the temperature of the water is too cold, that could be slowly down your triops. In this case, either research heating lamps or raise the thermostat; if you are keeping your triops in a small container like most people do, an aquarium heater could be deadly.
yes it can because triops are cannibals.
Yes, this is because triops are racist, and the females tend to be darker.
According to Wikipedia, there are ten recognized species of triops, and according to "rainbowaq-triops", there are at least 15 known species of triops.
The Yew. Taxus baccatta is a fairly slow growing tree.
Yes, Triops are living creatures.

Provided you do everything correctly Triops will breed.
Under proper circumstances, triops can begin reproducing at about two weeks of age. Eggs will need to be removed from the tank and allowed to dry out, then rehydrated. Dried eggs can be viable for years if properly stored, so the timing of a new batch of triops is really up to the breeder.
