Semi-Aggressive Freshwater Fish for a Tropical Aquarium

You’ve may have seen tropical fish labeled as semi-aggressive and wondered if they were smart choices for your tropical aquarium. This label can be confusing, and not all fish earn it for the same reason.

What does semi-aggressive fish mean? It sounds like these fish are violent, but only part of the time. Like, maybe every now and then they just go berserk, but most of time they are calm and peaceful.

Well, not exactly. When a fish is labeled semi-aggressive it usually means, under the right circumstances, the fish can be very aggressive. Very aggressive means it could attack other fish and kill them, eat other fish as food, or relentlessly chase other fish around until they die of stress.

On the other hand, under the right circumstances, a semi-aggressive fish can be very docile. While we can never know exactly what a fish is going to do, we can predict with a fair amount of success how they’ll react in different situations due to their temperament and natural habits. This means, if we stock our tanks wisely, even a semi-aggressive species can be a very peaceful community fish.

The first step is to know the fish you plan to stock in your aquarium. In this article we’ll take a look at many common semi-aggressive tropical fish and what makes them potentially dangerous to other inhabitants of your tank. If you understand these fish before you stock them, you can make sure everybody gets along, and reduce the chances of aggression in your 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
