Yes, but you can only have one in there, and it must be filtered and heated.
They can survive, but they will not thrive. You should be looking at something 5 gallons+ if you want your guppy to live a long and happy life. Keep in mind that they are tropical fish, and room temperature will not usually be warm enough for them.
It depends on how many guppies, and how well you keep up the tank. In a ten gallon tank, I'd say no more than ten guppies, and do frequent water changes. 10-15% weekly. They need a filter and a heater, as well.
Well guppys are tiny fish so i have 2 say, wait, well that depens how many other fish u have in the tank here are some examples: If u have a little pet shark, five little goldfish, 4 neon tetras, and 2 clownfish, you should have 5 guppies. If u don't have a pet shark u could have 10 guppies. (new person) Well, technically it is a ten gallon tank. If it was, say, a ten centimeter tank in height and maybe a few inches in width, then maybe ten guppies, more or less, like the person above said. But a ten gallon tank is like pet-store material, so I'd say a couple hundred guppies in a ten gallon tank.
You can keep endlers guppies in a 1.5 gallon, about 2, if you maintain it (take some water out, take uneaten food out, ect.). you should keep the tank planted well because they enjoy it. You can buy endlers at petsmart. :)
Well, 4 guppies would be fine in a 2 gallon bowl, but they breed a lot, so you'll have to put them in a 10 gallon tank once there is fry [put the fry in the 10 gallon tank, not the parents!]. But if your just keeping 4 females, or 4 males, they can live in the bowl just fine. I would not put them in a 1 gallon, or 0.5 gallon bowl, though. It's not big enough [not as big as a 2 gallon bowl is]. You can feed guppies betta pellets, betta flakes, or even a broken goldfish flake, if your guessing what to feed them. If you just had goldfish, or betta fish that just passed away, use their fish food to feed your guppies. It won't hurt them, because guppies can and will eat just about anything you float on their water. Hope this helps.
This is not a good idea. When the angels are fully grown they will consider the guppies nice snacks. If you plan to move the angelfish to a tank with larger fish when they are fully grown, they do make suitable tankmates when small.
That is fine. You might consider getting some corydoras catfish.
You could add a shoal of guppies and simply allow them to breed which would certainly stock your tank well
If the water temperature does not get too cold, and the water continues to be aerated, then the darkness won't matter. Guppies survive perfectly well in the dark.
Well, it depends on their size. From what I've heard, you can put one inch of fish into a tank per gallon, so: 5 one inch fishes of 1 five inch fish etc. It doesn't matter about the fish unless some are aggressive and the others are not.
They can not go with there own kind but do well with guppies and larger fish...
Guppy's are the best fish for breeding out there, and you could of a school of 8 in a 15 gallon tank. They come in many vibrant colors.
