Sometimes, Two is Better Than One

As surprising as it is, some fish can get easily depressed in a tank all to themselves. Whether it’s for mating, friendship or to avoid depression, no one can know why for sure. Other fish prefer to live alone. That reason’s simpler to understand: fighting.

If you are mixing multiple types of fish together in your tank or adding more than one, look up information about that species or ask a professional for help. You don’t want to fall in love with your fish only to realize they will not live together happily. It’s always important to know beforehand.

Why Do Some Fish Need to Live Alone?

Some fish have an attitude. Things will go south fast if you pair them with another fish, even of the same breed. It could lead to fighting between the fish, and possibly, death. Here are 4 fish breeds that should live alone.

  • Piranha
  • Betta
  • Oscar
  • Paradise Fish

These 4 fish breeds are ready to rumble. It’s not advised to put another fish in your tank when you already have one of these fish inside. Fighting is likely to occur.

Fish that Prefer Pairs

While some fish like to fight, others are peaceful. They can easily live in a community setting and, in fact, prefer it. Some fish demand certain care, like water temperatures or special food. You need to make sure your fish are compatible with each other before you put them all in the same tank. Here are a few fish that should be kept in pairs or community settings.

  • Catfish
  • Tetras
  • Danios
  • Raspboras
  • Guppies
  • Swordtails
  • Plecos
  • Mollies
  • Corys
  • Loaches

These breeds of fish thrive in community settings. Without a pair, their loneliness could lead to death. No one wants that to happen. Keep in mind that some stores, like PetSmart, even advise you on the breeds of fish that would live together well. Always research and ask for feedback before you move your fish into their new tank.
