Amazing And Cool Freshwater Fish For Your Tank

Andy Birks from SIMPLY AQUARIUM shared with Healthy Lombard that over the years he and his team have owned most of these fish we is writing about between us. So thy have spent a good while discussing their favorite cool freshwater fish!

The majority are easy to keep and great for a community tank. He also added some striking but tricker ones if you have more experience. You’ll see he has defined the care level needed for each fish.

1. Peacock Gudgeon

  • Care Level: Easy
  • Max. Size: 2.5 to 3 inches
  • Temperament: Peaceful
  • Min. Tank Size: 15 gallons
  • Water Temperature: 72-79° F

The many bright colors of the Peacock Gudgeon make this a very cool freshwater fish!

Make sure you have a well-planted tank with plenty of hiding spaces. Whilst they are very social fish and great for a community aquarium, they do like time to themselves.

It’s best to have one male and two or three females in a tank, as males can be territorial with other males [1].

Peacock Gudgeons are omnivores, although they lean towards a meat-based diet. Feed them frozen or freeze-dried protein-rich foods like brine shrimp or bloodworms [2].

Suitable tank mates include barbs, kuhli loach, tetras, cory catfish, and rasboras.

2. Boeseman’s Rainbowfish

  • Care Level: Easy
  • Max. Size: 4 inches
  • Temperament: Peaceful
  • Min. Tank Size: 30 gallons
  • Water Temperature: 72-77° F

The Boeseman’s Rainbowfish is a perfect choice for a striking freshwater fish.

A well-planted tank with plenty of room to swim will show off these fish to the best effect.

They are omnivorous and should be fed flakes, and live and frozen foods which will help enhance their color [3].

They are very social and should be kept in a school of at least six to eight fish.

The Boeseman’s Rainbowfish will also do well in a community tank. Barbs, tetras, cory catfish, danios, gouramis, guppies, or loaches would all make excellent tankmates.
