Best Freshwater Aquarium Fish

The Top Ten

1 Angelfish

Tall, slim, and majestic. They slowly swim around. A pleasure to watch.

Captain winnih the poop

2 Discus

Without a doubt the most beautiful freshwater fish. I'd make it number 1, but its difficult to care for.

They are beautiful fish but are very hard to care for. They need a 75 gallon tank. They need perfect water conditions.

3 Betta

If you're looking for an easy to care for fish, get a betta!

Bettas are cool fish, but they're semi aggressive, so they aren't great around others. - Swellow

I have a betta fish

Bettas are just the coolest fish. I have one in a Fluval Spec I on my nightstand. - Blue_Devereaux

4 Cory Catfish

These fun little guys are fun to watch and are very versatile. A fish for all aquariums.

5 Neon Tetra

These are awesome

Possibly the most popular aquarium fish. You must keep them in schools to see how awesome they are.

6 Plecostomus

The most helpful clean up fish. So many cool varieties. (Try zebra, cactus goldy, and royal)

7 Glass Catfish

Who doesn't want a see-through fish?

8 Black Skirt Tetra

The most beautiful tetra. It is a pleasure to look at (not the long finned variety)

This is number one

Increadable! These are very handy and school very well.

9 African Cichlids

Although not compatible with any fish, African Cichlids come in great colours and sizes can differ to 3cm to 30cm.

10 Upside Down Catfish

Funny little guys. They love to hover underneath driftwood.

The Contenders

11 Arowana

Best fish, real beauty watching its elegance

12 Goldfish

Goldfish are one of the smartest aquarium fish, with R2 fish school you can make them do amazing tricks! Also they are very long-lived and have a better memory than not hominid primates, also they come in slim and fancy varieties... Even though of this, is sad that people select fish as "ornamental" or "decorative" objects without caring about what they can do. Almost everybody considers goldfish "throwaway", "useless" or "simply stupid/ugly/bait" and that makes me feel sad, also the fact that people think they can live in bowls, simply no, the oldest goldfish lived alone in a 10 gallon, but 10G isn't 1G, and also if you want your goldfish to grow properly with a small tank simply buy a fancy one, they require 10 gallons each one (in my experience this has resulted good for me, but as they are social, a 20G with two is better [if you will start criticizing me because of the "40/20 gallons per goldfish rule" I must say that's for people that don't have enough interest to make 10% water ...more

I personally prefer Goldfish to the variety and the affection they give to their caretaker. They're smart enough to tell who their owner is, and just a family member. They're smart enough to do tricks like. Fetch, going through hoops, soccer, and etc. My Goldfish always comes to the front part of the tank when I walk near it.

13 Bolivian Ram
14 Blood Red Parrot Cichlid

Awesome fish! They are weird looking, large, and come in all sorts of bold primary colours. Problem is, they are not very compatible with other fish

15 Glofish

Glofish is so pretty

I have glofish

16 Oscar

Love them they get huge and albino ones are awesome!

They are very common but can grow to 1 foot 2 inches. Need a 50 gallon tank. Very aggressive, and if you what some thing with it the one fish will need 75 gallons.

Have true personality. More like a pet than almost any other fish.

Oscars are the best I have one named chomper and he is huge they are the funniest fish ever they can bite though
