I think that whatever you get out of your friends tank needs to stay wet with some aquarium water to keep the bacteria from dying. Someone correct me if I'm wrong....
What I did with my friend's tank ornament is kind of funny. He brought it to work in a large plastic ziploc bag full of tank water, inside a black garbage bag. So I had this ice cream pail with a garbage bag sitting inside it in my office for the day.
When I got home that evening, I dumped the tank water into my tank and put the ornament in it.
I agree with Joe, cardinals are probably better for a newbie, although neons seem tough to me as well. Glowlights are another good option as well as other neon-like tetras like January tetras.
Thanks again for all the advice. I think what I would like to do barring any opposition from those that know better is this:
3-4 Platy's - females for now to keep the population down!
3 Panda Cory's
Oto's and shrimp.
How does that sound? Too much bio load?
I think the neon/cardinals will wait until I have some more experience. Maybe another tank will have to be found!!
I'll keep in touch with the cycling since I'm bound to have questions.
you could also think about getting some white cloud minnows...around here adults are $1.50,but i found some fry that are used as feeders for 8 for $1. they are really cool
I love my white clouds. I have 5 and 3 cories in my 10 gallon with lots of ferns to keep them happy. I find keeping the temp around 70-72F keeps them the most active.
Just because you won't have any males doesn't mean that there won't be babies. Female platies are often sold pregnant, and if I understand correctly, they can store sperm for a while. But you shouldn't have a problem as they eat their own fry.
Edit: One more thing! Do not buy platies that have clamped fins if possible. It is an indicator of questionable health in most fish, but in my limited experience it is quite pronounced with platies.
