Neon tetras are gentle and won't harm other fish in your tank. When stressed, they can fight. Avoid overstocking and monitor water quality to keep your tank safe.

Guppies are active, colourful fish. They're little, so they won't harm other fish in your tank, but they're very active, so if you want a calm aquarium, avoid them.
Fancy Guppy
Plecostomus eats algae while clinging to glass. People who desire a calm aquarium may not like them. When their needs aren't addressed, Plecos get cranky. Plants die.
Otocinclus Catfish
Aquarium cories are popular. They reside in the tank's bottom and eat leftovers. Their work keeps your water tank clean.
Cory Catfish
Hardy aquarium fish, zebra danios. Small, docile, and playful. Zebras lay eggs, not live young, so your tank won't be overrun with guppies, swords, and platies. Ideal number: six.
