Hiya Krazydoode and mikebrady, welcome to MFK!
I need to ask a couple questions about your taste in fish and about the tank,
first what are the dimensions of the tank, 80s can be short and wide or narrow and long, the wider ones allow for fewer but bigger fish, great tank to start with either way.
next what kind of accesories do you have, lights, filters, etc. mainly filters, big fish need heavy filtration but lightly populated tanks can get by with less.
And now the fun stuff. What kind of fish do you like, as a beginner you will probably want hardier, more forgiving fish than things that require specialty envirornments. That still leaves lots of choices. Some people like fish from just one area per tank and others mix them up, I do both. Do you like lots of small-medium community fish, predators, big fish?
Slender pikelike fish or beefy bodied bass like fish, colors, stripes, or silvers? Would you like territorial nesters that will breed for you like cockatoo apistos or dwarf pike cichlids?
Think about it a little and let us know, we all have different ideas about what goes in a fish tank but between us I bet we can help.
