1 Siamese Fighting Fish
I had one as a pet, and they are extremely interesting. They have so many different colors and are a very addicting fish.
It is very interesting to watch because of its long and colorful fins
My Siamese Fighting Fish (Betta) died almost a year ago:(

I WANNA EAT IT! - Misfire
Catfish, of any kind, are fascinating, and it's their many kinds that fascinate me. There are giant catfish much bigger than people, catfish with poisonous barbels that stick out in front of their mouth, catfish that can electrocute you with 400 volts of electricity, catfish that like to hang out upside down, and so many more.
There's so many kinds, and different sizes! Just watch river monsters #season premier
3 Moray Eel
In my opinion, moray eels are the best. For starters, they look positively awesome. They also have a second set of jaws inside their mouth, and can reach up to 13 feet long, with some weighing 66 pounds.
4 Thresher Shark
With their long tails they are a definitely a strange sight, but a cool one. They use their amazing tails not only for swimming, but for stunning fish. That's right, they swing their tails at schools of fish, dazing the prey they strike, and making it easy to catch.
In adults, all but one species possesses lungs and are able to use them when their watering holes dry up. They tunnel just below the surface of their dry pool and survive on air in a state of dormancy. This makes them cool in my book.
The blobfish is a deep sea fish of the family Psychrolutidae. It inhabits the deep waters off the coasts of mainland Australia and Tasmania, as well as the waters of New Zealand.

A piranha or piraña, a member of family Characidae in order Characiformes, is a freshwater fish that inhabits South American rivers, floodplains, lakes and reservoirs.

These are so beautiful. They have such pretty colors and patterns.
A viperfish is any species of marine fish in the genus Chauliodus. Viperfish are characterized by long, needle-like teeth and hinged lower jaws. A typical viperfish grows to lengths of 30 to 60 cm.
Their mouths are so amazing with their abnormally long, spear-like teeth, and they have elongated bodies like snakes.
They are a cool fish with an interesting name. Their name comes from an Indonesian word "arwana", meaning "fish of paradise".

Imagine a pack of piranhas that are bigger than people! A terrifying, but awesome animal.
