Tank Size For Fish

The guppy has to be my favorite fish by far, not just because of its cool colors but also because of how easy they are to care for. When it comes to tank requirements for this fish, you don’t need anything fancy; just a simple tank setup will do. If all you have is a 5-gallon tank, I suggest you go with 1 male guppy, although a 5-gallon tank is not very ideal and I would avoid it if you can. If you have a bigger tank, maybe a 10-20 gallon tank, you could have anywhere from 3-8 guppies, or maybe more if you are willing to do frequent water changes. A simple rule for basic fish like the guppy is that for every one inch of fish, there should be 1 gallon of water. Generally speaking, guppies are about 2-2.5 inches when fully grown, so consider that when deciding how many guppies would be good to get for your size tank.

Water Parameters

As for water parameters, guppies generally like harder water with more minerals in it. They prefer to stay at a temperature of 70-82°F. I recommend you keep it around 78°F, as I have seen them perform best at this temperature. They also prefer a high pH, so if your tap water happens to be well water, then guppies should be the easiest fish to keep.

Guppy tankmates

Guppies are very friendly fish; they can be housed with almost any other freshwater fish, although there are some that don’t get along. You mainly want to avoid fish that have a tendency to nip at fins; aggressive fish should not be kept with guppies.

Guppy Diet

Guppies are fish that will eat almost any kind of food you put in the tank, but that doesn’t always mean that’s what’s best for them. There are lots of different kinds of food on the market that are made just for guppies or livebearers. The main foods I would recommend you feed your guppies are brine shrimp, Hikari Fancy guppy, different kinds of live foods, and the classic tropical flakes.
