Semi aggressive tropical fish list

List of Tropical Fish for Freshwater Aquariums

When setting up a freshwater aquarium, you want to make sure that you understand which fish will get along. The last thing that you want to do is have your tank proper set up and acclimated, and then a few weeks, or even days, after adding a your initial fish, one or two start to nip and bully the others. This will severely stress out the other fish.

You want to make sure that you keep community fish with community fish, semi-aggressive with semi-aggressive, and aggressive fish with aggressive fish. But, in terms of aggressive and semi-aggressive fish, you want to make sure that you keep similarly sized fish in the tank. With aggressive fish, you want to keep one species per tank, as well.


Freshwater aquarium

by sage9x

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
