Temperament Fish

Is a general guideline of the species demeanor in the average aquarium. It is important to understand that each fish can have its own personality, and may act differently when subjected to a different environment, or when housed with different species of fish. Stocking order can also will play a role in animal's demeanor in the home aquarium. This is a guideline that when cross-referenced with our compatibility chart (insert link), will give you an idea of what behavior to expect with the species in question. 

Peaceful:
Species within this category do not pose a real threat toward other fishes, and are very passive and sometimes reclusive in nature. 

Semi-Aggressive:
Species within this category are normally active fishes, and may occasionally chase or show aggression towards one another or similar shaped tankmates. When placing Semi-Aggressive species in your aquarium, be sure to introduce them after the smaller, more passive fishes have been established. 

Aggressive:
Species within this category are normally territorial and bold fishes that should be housed with fishes that are of the same demeanor. Aggressive fish should be housed in a species only aquarium, and if adding them to displays with semi-aggressive tankmates, they are the last fish introduced into the display aquarium.
