The basics:
Guppies are very popular and fun to have. They give live birth instead of laying eggs so a challenge to keeping Guppies is separating males from females or else finding homes for all the babies. Luckily it's easy to tell which ones are males and females.

Guppies originated in northeast South America but are found all over the world now. They are very easy to care for and stay small which is why they are so popular. Guppies are easy to feed and prefer flake food, they stay too small for most pellets but would go crazy if you gave them frozen brine shrimp as a treat.

The Guppy has an elongated body form and shows great variation in both color and patterns. Males have color throughout thier whole body and longer fins than females. Females have grey bodies with the only bright colors in their tail and dorsal fins, which are short and rounded compared to males.

When a female is pregnant her belly gets very large and has a visibly darker area where the eggs are. When fry are born they are colorless for a few days, if she isn't watched carefully or separated when she gives live birth the fry will get eaten by tankmates.

Guppies are extremely peaceful and can be kept in a community aquarium. Male Guppies may fight among themselves at times and you will need hiding places if housing more than one. Guppies should be kept in groups of 3 females to every one male, this reduces stress and the likelihood of fighting.

Guppies need a tank size of at least 5 gallons. It occupies the middle layers in a tank and thrives in an environment with plenty of live plants as well as a few floating varieties to keep the lighting subdued. They are tropical (warm water) and need heaters in the winter to maintain a temperature of 76 degrees. They can be vulnerable to fungal infections in fresh water and have the best health when a little salt is added to the water, at low levels this is safe for most fresh water fish.
