So i know there is freshwater, and reef, and marine/ saltwater tanks, but thats not where I'm heading....
My question is what type, or variety, of
freshwater fish tanks are there
Like when I go to the pet store (aka Pet Smart), with each kind of fish they have, its says like what type it is, like....
*Tropical Community
*Semi-Aggressive
*Aggressive
So I was wondering, is it proper 'lingo' or what-not, or do people go around saying like "I got a tropical community fish tank", or a "I got a semi-aggressive tropical community"

?
Or is that not how it goes? Like I'm thinking of setting up a 'freshwater great lake community' fish tank... is that a real term? I was thinking of how I would look for resources for that kind of tank, or any other type of tank.
Thanks so much in advance for your help,
