Hailing from Mexico and Central America, only the male fish possess the unique swordtail, making males and females easy to distinguish if you want to breed them. Although not a fish, the African Dwarf Frog is a unique, low-maintenance addition to freshwater aquariums. These frogs are entirely aquatic, which means they never need to leave the water. They can coexist with non-aggressive fish species and get along well in community tanks.

  • They are often less hardy than common Goldfish, which can make their care slightly more difficult for beginners.
  • The only time they become aggressive is if there is more than one male swordfish in the tank.

There’s no denying that these colorful species are some of the best turtles for aquariums, but sometimes, they are too big for your tank. The complexities of these care needs depend on each turtle’s species. You must understand their features and habitat needs to determine the best freshwater turtles for your aquariums and level of expertise. The bristlenose plecostomus is a species of catfish with distinctive tentacles around their snout. While most catfish reach lengths of around 20 inches, the bristlenose plecostomus is much smaller at just five inches and has a lifespan of around 10 years. Known for being fantastic little vacuum cleaners, if you want a tank that looks spick and span, this is definitely a species worth considering.

Even if you’ve chosen hardy fish as your starter fish, you’re still going to expose them to toxins, which will eventually reflect in their health. It goes without saying that adding small fish to a tank with larger fish is also a no-no, since the bigger fish will mistake the smaller ones for food. So, you’ll need to perform water changes and clean the tank regularly to keep nitrate levels under control. If you add fish to a tank that hasn’t gone to a cycling process, ammonia levels will spike because of the waste fish generate.

Stable water conditions and a balanced diet of flake food, supplemented with occasional live or frozen treats, will support their health and vibrant colors. Beginners will appreciate their easygoing nature and the lively dynamics they introduce to the tank. While they can adapt to a variety of water conditions, maintaining clean and well-oxygenated water will ensure their health and happiness. Their diet should include sinking pellets and occasional live or frozen foods to mimic their natural foraging habits.

Beginner will often select fish based on their personal preferences without much regard to water conditions and compatibility.

Use the fish net to remove any dead plants or fish and use the algae scrub to clean the glass surfaces and other tank decorations. Tank maintenance should be carried out regularly to keep the tank clean and toxin levels low. Even though some fish are known to get along, it’s still a good idea to monitor tank behavior when building a community tank. Platies, Mollies and Guppies are great beginner-friendly fish that get along with each other in a community tank.
