sleet - FIRSTLY. You should have put this second question about the exact same topic as before (Sept11) back under the Sept 11 post and your first question by using the reply button at the bottom. Do not create a new post about the exact same topic; use the old topic/question to continue your ideas about fish in an aquarium .
SECONDLY. If you are as you say assist. mgr. of animals you better start getting it together by learning and reading up on what you are supposed to be doing in maintaining the fish. All fish need the same basic requirements; good water quality and nutritious food. Don't learn by "trial and error" when working with live animals. Do some reading and studying from good books about raising animals including fish. The pet shop should have racks of magazines and books. If they don't the library does; remember the library? Just liking animals does not mean you automaically know how to raise or care for them. As I said twice before read books and learn what to do for specific animals or groups of animals. Ask a specific question and I will try and give a specific answer.
Try
www.aquariumfish.com . I'm not sure what's there but it is a site from the magazine I subscribe to: Aquarium Fish, Fishkeeping - The Art and the Science. Your pet store probably carries it. They had an article about raising native fish that I can look up for you if you need it. The library has books on raising native fish.
I'm still not sure what information you want. Ask a specific question. I answered what to feed small bluegill and about filtration and water quality for them in the other Sept 11 post. Go back and read it again. Small bluegill will eat pretty much the same thing as goldfish or oscars or ciclids (which are tropical sunfishes). If to quote you, "you know what to do" what other opinions do you want?
Just out of curiosity, and since your are the assist. animal mangr. of the pet shop fishes, how many total fish die in all the tanks each week? And how many tanks in your pet shop??. Just an average number of dead fish each week is okay. All pet shops clean out dead fish daily. Since you may not open the store in the morning and remove the dead ones will you ask the manager my question?
PS Put a sign up on the bulletin board in the pet shop for a used larger aquarium. Probably can get one cheap or in the newspaper want ads. Live near me??, I will give you a 40 gal long or 20 gal hi free. When do you want to Come and get it?.
