What are some factors to consider when selecting an aquaculture species?

Tank size, fish's max. size, preferred water temperature, plant needs, aggression, water chemistry standards, your own fish-keeping experience, fish's preferred food (live, flakes, veggies, etc.), other fish in the tank. these are the most important ones, if you have found a fish you like, go to liveaquaria.com for more info (find the type of fish and read its requirements).Hope I helped!
