Guppy's are live bearing fish which means that they give birth to free swimming fry, they also breed very quickly, imagine them like the rabbits of the water.
One time a female Guppy has mated they will give birth for up to six months consecutively, therefore you must have a huge tank to be able to handle to the giant amounts of new fish that the Guppy will introduce to your tank.
The first brood will be delivered after 25 to 28 days and will usually be around twelve to0 fry, the second can range from0 to fifty and consecutive deliveries of up to a hundred or more fry can be delivered, all within0 to ninety days apart.
However not all the fry will survive, the brother will start to eat her kids after they delivers her last fry in the event that they are not separated, and they are going to be of coursework vulnerable to other tank mates who will be looking for a free meal. The larger the brood that is delivered, the more fish that will survive.
You can however help the survival of the fish along. Breeding traps are cheap, come in various designs and are very effective. Floating traps are both moderately priced and are basically floated within the tank, the pregnant Guppy is placed within the trap near delivery time and the fry basically fall in to a chamber below the female safely. One time the female has delivered all of her fry they can be released back in to the tank after a resting period of0 hours, any longer will stress the fish.
So how do you tell in the event you have a pregnant Guppy or not? It is actually very simple to distinguish female and male Guppy's, the male usually has vivid colouring along its stomach and fins, his anal fin will be long and narrow. The female are usually much duller in colour and have a rounded anal fin. When a female becomes pregnant you will notice her stomach becomes rounded and bloated with a dark spot towards her rear called a Gravid spot, as the fertilised eggs create this spot will become very black.
Watch the female every day, they don't all act the same way but in my experiences they have an inclination to hide away and try to discover a lovely place for delivery, this of coursework is not always feasible with the male Guppy chasing her around the tank. Because of this it is important to have a ratio of at least three female Guppy per male. It ought to take around to six hours to complete the delivery but it's been known to take around twelve to fourteen hours. Also in stressed females they have been known to deliver a quantity of their fry then cease and give birth again a few days later. It all sounds very complicated but as long as you keep an eye on your pregnant fish everything will be fine.
