Semi aggressive tropical fish Compatibility

Compatibility Between Freshwater Tropical Fish

Freshwater tropical fish fall into different groups based on basic compatibility, as not all fish species can cohabitate comfortably without aggression or territorialism. Some freshwater tropical species are naturally more compatible than others, while some species can be housed only with similar species--if any at all. Compatibility is an important consideration when choosing tropical fish species for an aquarium.

Compatibility Types

Freshwater tropical fish fall into different compatibility groups based on their ability to get along with other fish, whether larger or smaller. Community fish are generally friendly toward species of the same size or smaller, but not all community fish are universally compatible with one another. Semiaggressive fish are friendly toward fish of the same species but can be aggressive toward certain other species, especially over territory. Aggressive fish are compatible only with larger fish or fish of the same species; otherwise, they can create territory issues and cause harm to one another.

Community Fish

Most small tropical fish--such as neon tetras, white clouds, guppies, corydoras, small plecostamus, ghost shrimp and rasboras--are community fish. These fish do well in small and large groups, and in mixed aquariums with several species in one space. For these fish to cohabitate comfortably, you should provide them with a warm-water environment and at least 15 gallons of space. Because of their relatively small size, these fish are not generally compatible with larger or more aggressive species of fish.

Tetras

Larger tropical fish--such as swordtails, danios, mollies and platies--and larger tetras, such as black skirts, serape, red eye, painted and black neon tetras, are community species, but they do well only in smaller groups, and these fish are not compatible with most other species. Each fish in this group will do best with members of the same species, especially in small schools.


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
