Guppies have been a staple of the aquarium hobby for generations. There are countless color varieties of guppies. Males tend to have more vibrant colors than females, and have longer caudal and dorsal fins. Many guppy keepers may start out with only one or two fish, but being live-bearers with long-term sperm storage, you may be in for a full tank before long.

Molly fish are one of the most popular starter fish in the fishkeeping hobby. These fish are known for their low-maintenance care requirements and wide variety of colors to choose from.
