I've been keeping fancy guppies in my 75 liter tank for about 6 months now. Guppies are VERY easy to take care of. Currently, I have 4 males, and 3 females. At one time, there were 4 males and 4 females, but my favorite female died while giving birth...go figure. That is pretty much the only downside of having them, is their rate of reproduction. You can count on having to chase the little babies around the tank with the net about once a month, but I usually have to do it more often. I did kept a male betta in the tank with them at one time, but the guppies had already been in the tank for 2 months, and I suppose became territorial, because a short time later I found my betta missing pieces of tale. When my betta got "Ich", he naturally passed it on to my Guppies, but only 2 of the 4 females got it, and no males were affected. My betta, now in his own 8 liter tank, shows no aggression towards the larger babies which I occasionally have to place in his tank. For someone that has no idea what to do with the baby guppies which are overpopulating the tank, this may be a good idea to try while trying to find a "Mom & Pop" petshop that would take them.
My experience with guppies is a GREAT one. They're extremely friendly with the other fish in the aquarium. When I introduced them to the tank, it was just my baby molly living in there. At first they didn't know what to do with the molly, but now the three of them swim around like crazy. They're extremely peaceful and welcome any other kind of fish into a habitat. They're great fish, really they are. And they don't need a big tank either, which is a good thing.
No one has mentioned how important it is to put salt in the guppy tank. I treat mine as if it is a brackish water tank. I have Angel fish in another tank. I would never mix Angels with guppies because their water needs are very different. They will both suffer in the same tank. My guppies are in a species tank. I find species tanks to be the most beautiful because you can really focus on the needs of one fish without compromise in decorations, lighting, plants and water chemistry. Each tank is its very own unique world. Websites like this one are a great education. Thank you!
I keep guppies in a pond on my patio. They were my first fish (aside from Valentine the betta, which I had when I was three) and have lived through the stupid mistakes that I made when I was first starting out. At first I had 2 females and 2 males and put them into the pond. Within a month I had tons of fry. After a few months it was winter time and I was at my mom's house. I arrived at dad's house the next day only to find a pond full of my poor dead guppies. It had gotten too cold, but I decided not to get more until next summer so that I wouldn't have the same problem again. After removing all of the guppies I pretty much ceased care of the pond. By spring I couldn't wait so I decided to get more guppies. I decided that it would be neccesary to clean the pond and while I was cleaning it I discovered 4 adult guppies that had survived from the time that they were fry. They had hidden and lived without any care. I was overjoyed and soon had tons of fry once again. They are still living to this day and breed like crazy. Some of the males' tails are truly unique and look like works of abstract art. You really have to see it to believe it.
The Fancy Guppy is easily my favorite kind of livebearer. Not only are they hardy and easily bred, but they are beautiful and are available in a myriad of bright colors. I would highly recommend this fish for any novice aquarist or child who is looking for a durable fish. They are happiest in a pH of 7.3, but are willing to adjust to many different levels. Due to their small size, they are great fish for aquarists with limited space and budget, but I wouldn't recommend housing them in a tank smaller than 20 L. Guppies are wonderful fish!
I have two aquariums with fancy guppies in them. The first, a 40 liter, has female guppies, black neon tetras, glo-lite tetras, and a pleco. The other tank holds all male guppies and two panda corys. In my experience ALL male guppies, regardless of age, pester the females, even if they are pregnant, to breed. If you do not want hundreds of fry, buy all males or all females. It is best, if you want your immature male guppies to reach their full potential growth, that you keep them in their own tank, away from females. This will help them focus their hormones on growing, not breeding. If you are planning on breeding your fish, buying males and females from different stores may work for a while, but if you do not keep up your tank (who wouldn't?) you WILL have inbreeding. Hope this helps, and good luck with your guppies!
