Freshwater aquarium fish aggressive

Aggressive Freshwater Aquarium Fish

As anyone who knows me would tell you, I am an aquarium enthusiast. I have three aquariums currently and I would love to have more. Through my years of experience in the aquarium trade, I have developed a personal opinion about some of the popular aggressive fish on the market. I have had a lot of experience with all the species in this list and I have had several specimens of each species.

1. The Arowana:
The arowana is one of the most interesting fish I have ever come across in the aquarium trade. This fish is literally a modern day dinosaur. The arowana is one of the most ancient species in the world and is quite similar to it's dinosaur ancestors. In Asian countries this fish is called the "Dragon Fish" and if you look at one you will know why. This fish is a very active at all times of the day. The fish will actually get very sick or even die if it stops moving because of its anatomy. The reason this fish is number one on my list is because it is active, it is aggressive, and it keeps to itself. The arowana is a top swimming species, spending most of it's time near the surface of the water. In general, the arowana keeps to itself and doesn't bug other fish in the aquarium; unless the other fish in the aquarium harm the arowana.

2. The Wolf fish
The freshwater wolf fish is a ferocious predator. This scary looking fish is called a "Piranha eater" in the amazon, and the name seems to fit when you see the size of it's teeth. Wolf fish are very fun fish to have in an aquarium. They will attack feeder fish as soon as they hit the water, they are more than capable of disemboweling any fish that looks like prey. The good thing about wolf fish is that they don't really mess with other fish. They are fairly territorial and will nip and any fish that tries to take his spot but nothing serious.

3. Peacock Bass
The peacock bass is one of the most renowned freshwater game fish in the world. The peacock bass' name comes from the beautiful coloring of an adult. Not only are the beautiful fish, but they are also capable predators. Peacock bass are very active fish and will constantly be meddling around. This is a curious fish that will always be looking for trouble. Peacock bass aren't essential tank mates because they like to mess around with other fish. Also they never seem to learn their lesson when they get nipped at or chased away. The fish is an awesome fish nonetheless and would make a great addition to any aggressive large aquarium.


Freshwater aquarium

A saltwater aquarium is going to be a massive time suck and a money pit. I advise against it. I really enjoyed my freshwater aquarium, but I never really had a problem with hard water. They make water conditioners for that, though.
I really enjoyed my freshwater aquarium. It was not that expensive, and if you get the right kind of fish, they are hard to kill. I stuck with Rafael catfish(hard to find the spotted kind), senegal bichirs(some people call them dinosaur eels), chichlids(super aggressive), and oscars. Don't forget to also include an algea eater(like a pleco), and several mystery snails

Adult Corydoras Catfish to a good home.

I have a twenty five gallon tall planted aquarium and I bought a tiny little cory cat not realizing at the time that they grow to be ~3 inches long. I have plenty of room in my tank but honestly my cat has become too aggressive to other bottom feeders like algae eaters for me to keep him. The aggression is probably due to the size of my tank and my oversight. He has never been aggressive to mid or high water community fish. I am happy to give him away to someone who has a good size freshwater aquarium. I can provide a picture if necessary but a quick Google of corydoras will give you a good idea
