Best Freshwater Aquarium Fish

The Top Ten
1 Angelfish

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

2 Betta

My betta Jellybean is the cutest little dude I have ever had. He loves his helpings of bloodworms and has a little spot he loves to hide in his tank.

Bettas are awesome and I love to see them thrive in large clean, filtered, and heated tanks instead of those small dirty bowl ignorant people put them in. They are living creatures not d├ęcor.

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

3 Cory Catfish

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

4 Plecostomus

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

5 African Cichlids

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

6 Discus

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

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

7 Glass Catfish

Who doesn't want a see-through fish?

8 Neon Tetra

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

9 Oscar

Oscars are alright, I do they're fun to have around. That they're cool looking. For people on a budget I think Oscar are not the right pet for them. Oscars are decently expensive and they need an even more expensive tank. Oscars are walmart cost about 11, other places I seen them at small sizes for 14 dollars. The tank they're required to live is a 55 gallon tank. That can be expensive.

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.

10 Black Skirt Tetra

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

The Contenders
11 Platy
12 Swordtail
13 Bala Shark
14 Goldfish

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.

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 changes dairy, and ten gallons is enough for them to grow to 5" long {medium size, this won't shorten it's lifespan, just before you say I'm cruel} also with good cycling bacteria stablished, and a good filter, everything will be fine in water chemistry/quality]) also the fact that they can know who feeds them (along with angelfish, arowanas, bettas and other clever fish) also their hearing is by far more developed than ours and can recognize who plays classical music!, as they can know who heared before can use certain movements and sounds. If this list was for the most clever fish it should be like: 1) arowanas 2) angelfish 3) goldfish 4) betta and 5) oscar.

Goldfish, bettas and arowanas some of the fish you can easily train... Anyways, this was for aquaria in general and not "Top ten most clever fish"...

15 Upside Down Catfish

Funny little guys. They love to hover underneath driftwood.

16 Arowana
17 Bolivian Ram
18 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

19 Guppy

Guppies are very colorful and reproduce very quickly.

Very beautiful looking with brilliant colors, must have if you love smaller fishes

20 Glofish

I have 4 tiger barbs, 2 tetras, and 1 shark and they are sweetest coolest little things!

21 Glo Tetra
22 Gourami
23 Crayfish

Not a fish, but its still a cool one.

24 Molly

I love balloon mollies. So chubby!

25 Senegal Bichir

A fantastic fish that is fascinating to watch. An ambush predator in the wild, very cool to watch in your home.
