    Guppies

    HI...my name is Hope.. I am new to the fish thing and how to keep them going, I used to have a tank but just didn't care much about it, but now my boyfriend and I just started in on it. We have many fish but we are trying to breed our guppies. I guess the main question that I want to know for all my fish is... How do you tell the difference between male fish and female fish. Please help me... Thanks!!

  • Hi Hope. This is what my books says on breeding of guppys and million fish (Poecilia Reticulata) Breading: this prolific fish is easy to breed The period of gestation is four to six weeks. The 20-100 young grow grow quickly and reach maturity in about six months. Breeding temperature 23-28c. The young fish should be provided with good cover in dense vegetation. Although easy to breed, the responsible amateur should only breed those pairs that will preserve the particular color pattern and fin shape he observes with the parents, and this does involve a elementary knowledge of genetics and information about the pedigree of the parents. There are now many Guppy societies around the world and the interested amateur should not only study the literature but also establish contact with a society before breeding these fish otherwise he runs the risk of encouraging poor strains. Female's are less vividly colored and have a smaller dorsal fin then males. (The complete aquarium encyclopedia of tropical freshwater fish 1995) As far as I know from experience guppys breed really easily. You can buy a guppy fry holder (available at any local pet store) to hold the babys in once they are born. and the males are alot more colored then the females.

  • Please stay away from the fry holders. I raised two platies that way and I am convinced that's why they were stunted. They are great for a temporary holding area until you can move them to a small 5 or 10 gal tank. I recently read some information in I think the new Fish magazine that also supports my contention that the breeding traps deter growth as well as causing the parent some stress.

  • I will tell you my experience with guppies. Leave them alone in a tank that has some areas of dense vegetation and hiding places for the fry, and you will have more guppies than you know what to do with. A friend of mine moved leaving with me her 7 guppies. I now have about 35 adults and 17 fry as we speak. I feed them fry food most all the time as the fry can get to this as easily as the adults. The difference between the males and females. Males are smaller than the female, more colorful and have streamlined bodies. The females' colors are not as pronounced and they are fuller in the belly area. When pregnant, you will see a dark area at the vent. My guppies are young, and I rarely see more than 7 or 8 fry at a time, however, you need to look every day as the more "pairs" you have, the more fry you will have. The fry are really very smart for being so tiny. I never separate mine, and I cannot tell you for sure that "some" of them don't get eaten, but generally I always have fry swimming with the adults or hanging out in the plants away from the adults. Don't worry about "trying" to breed them. When they are old enough, they will do just fine without any help from anyone. My only question is: You mentioned that you had "many fish". What else do you have in the tank with the guppies. If there are other species of fish, you probably will never see any babies as these fish will "definitely" have the little ones for lunch. And it is almost impossible to sit in front of the tank "watching" until the babies are born so that you can retrieve them. For success, I would move the guppies to their own tank. Good luck, and let us know if we can help you further.

  • Ditto with Kick. My platies escaped my hiding under driftwood and plants. I should have just left them there and they may have grown to a reasonable size. Just make sure you do have lots of hiding areas for them and if you have any swords look out they will really chow them down.

  • I actually raised my fry in those breeder nets with great success. Of course, I would move them out after three weeks or so because of several reasons: 1. They were big enough to look for food on their own instead of having it thrown in front of their faces for easy finding 2. They were getting too big and were crowding the net. 3. There was a new batch of fry, which was small enough for their older brothers and sisters to eat, which they did once, and from which I learned my lesson. However, keeping fry in the net for long periods like I did took some degrees of maintenance, such as having the filter's outflowing current hitting the side so that newly filtered freshly oxygenated moving water would flow through the box. Stagnant water in the box would create bad water conditions within the box. I would also occasionally wash out the nets and parts because of the accumulating leftover food and poo. Snails in the net actually helped keep it clean though. Keep in mind that I am talking about the net breeder. I would have to agree with Joyce the plastic "breeder" box would cause growth problems and are best kept as temporary containers. So for longer term isolation, I recommend using the net breeder as long as you maintain it a little and allow fresh water to flow into the box.

  • Good point IBOY and yes I had the problem with the plastic breeder box. The stunted platies did live for over a year just looked really weird. I still think I would go with the small 5 gal and sponge filter, but I guess if you are on a limited budget the net breeder would help.
