Fishtank filter: I have a 125 litre community tank with a mixture of tetras, catfish, zebra fish and one large angel. All the fish get on fine. I'd like to get another angel fish (a small one) - does anyone foresee this causing any problems? Would the original angel fish accept another one?

I want to get a small aquarium. What are the types of fish that are the cheapest and easiest -- read: low maintenance -- to take care of in terms of feeding, changing the water, etc, but at the same time, are pretty to look at? Any additional advice on tanks/filters is welcome too.

Instead of planting my plants directly in the gravel of my aquarium, I was thinking of putting them in pots. Clay pots are fine, I think, but I was curious about plastic pots. Anyone out there know if those are safe to use? No toxins leaking into the water? I wouldn't even know what to test for. Home Depot sells a lot of these cheap.
