7 Best Freshwater Fish for 10 Gallon Tank

Owning a nano-sized freshwater tank comes with many privileges. They are relatively easy to manage, low in equipment cost, and water changes are straightforward.

Due to the size of these tanks, you will be somewhat limited when making stocking choices. In this post, I will propose my top 10 favorite centerpiece fish for 10 gallon tank. Do you think they are truly suitable?

1. Cherry Barb​



Unlike many barb species, Puntius titteya is very gentle and friendly, and can coexist with other fish species in a community. Keep six or more schooling fish and you’ll be amazed at how their red color stands out brilliantly against the green foliage of a planted tank. Moreover, they easily breed and lay eggs in dense vegetation or breeding places. If you’re looking for a vibrant, eye-catching addition to your 10-gallon tank, you can’t go wrong with cherry barbs.

2. White Cloud Mountain​



Minnow Tanichthys albonubes comes in regular and long-tail forms, but our favorite is the gold variety for its peach-colored body and red fins that stand out in the aquarium. This cold-water swimmer can live in an unheated tank, making it ideal for office building or classroom environments. Additionally, their gentle nature makes them perfect companions for dwarf shrimp or even bettas (as long as there are enough hiding places). Like many fish on this list, they are easy to breed in a species-only tank, especially when provided with plenty of aquatic plants and good food.

3. Green Neon Rasbora​



This tiny schooling rasbora deserves more attention from aquarists for its radiant color. The shiny green is a rare color rarely seen in the aquarium hobby. Place a group of six or more together (especially in a blackwater tank with tannins) and the brilliant shimmering light from their scales will attract everyone’s attention, even from across the room. They may be hard to find where you live in the world, but you can always try requesting them from your local fish store or ordering from a reputable online seller.

4. Fancy Guppy​



If you’ve never owned a guppy, you haven’t lived! In our opinion, guppies are peaceful fish, perfect for a 10-gallon tank. They have all the colors of the rainbow, often swim up to the glass to beg for food, and are voracious carnivores, always eating every last bit in the tank. Although they don’t live long, these livebearers will make up for it with the abundant fry they will give you. Feed them well, give them hard mineral water, regularly maintain your tank - and you won’t regret it.

5. Dwarf Platy​



Can’t get enough of adorable livebearers? Get yourself a few dwarf platies or teacup platies. They are about 1 inch long and not as big as regular platies, so a 10-gallon tank is not too small for them. Duckbills are great cleanup crew members due to their insatiable appetite and knack for finding leftover food buried halfway in the smallest cracks. Because of their unique mouth shape, they are even known for their ability to dig up and chew algae. Dwarf platies may not be the easiest to find, but their cute size and lively behavior make them worth the effort.

6. Ember Tetra​



Hobbyists who have never seen an ember tetra in person may be surprised at how small they are. They are half the size of a cardinal tetra, making them a great choice for a 10-gallon tank.

Their orange color is like the hot coal they are named after and hobbyists will be pleased to know that they can keep up to 10 of these small fish in a 10-gallon tank. Above all, they are known to school, which is a clear benefit of owning a large number of these fish.

7. Bumblebee Platy​



Hobbyists pursuing livebearers need look no further than the Bumblebee Platy. This rare color form of the Southern Platyfish (scientific name: Xiphophorus maculatus) has yellow and black colors like a bumblebee.

Bumblebee fish can grow quite large compared to some other fish on this list (adults can be about 2.5 inches long), so hobbyists wanting to add these fish to a 10-gallon tank should not add more than a pair.
