Plants - stems or potted?

Plants don't do well in pots in an aquarium.. that works in more of a hydroponic setup. You would be off planting them and use rocks around them or some other physical barrier until the roots take hold.

i think goldfish will wreck almost anything you add to the tank. you could try a aponogoten crispus or something similar. i had mine in a tank with some small goldies for a while and they did not destroy it, just nibbled the tips a bit and it did well in there. they ate my water sprite though, and i know they eat other plants.

Is this Elodea canadensis* or Lagarosiphon major** (both are sold as "oxygenating weed"? The former is a more reliable oxygenator, generally, although the second looks better (IME). The other thing to bear in mind is that in a pond during summer the light is orders of magnitude higher than what you can achieve in a tank, so you won't see the same level of oxygenation as you would in a pond.

*Canadian pondweed
** "Elodea crispa" - an invented name used by pondkeepers.

Although sold as a coldwater and pond weed, I've often wondered how L. major would do in a tropical setup. It's cheap enough to give it a try; even if the Sev and the Buenos Aires tetras just eat it it's better they eat that than my other plants.

Anyone ever tried it?
