Respectfully disagree. :)
I like the idea, although keep an eye on your stocking level.
They are similar in size and behaviour, but contrasting shape and colour.
I doubt you'll see much difference in terms of what part of the tank they occupy.
Thanks sepehr - I'll take your word for it that the plants in those photos are correctly IDed; when I googled Echinodorus quadricostatus I got this plant, but others as well. That does look like what I have, and certainly the runners are very similar, which was the subject of my original question.
Tiger barbs are well-known to be fin-nippers, and gouramis can be territorial - hard to tell without knowing the species, but I'm guessing dwarfs.
I would suggest you return the tiger barb and the aggressive gourami to the store where you bought them and, if possible, tell the person you bought...
Ha! I tried this just the other day. I was trying to give my cat some exercise, but the fish were more interested.
Love the dog and cat action.

Thanks londonloco, that's interesting and I will consider this method with my next tank.
sepehr, I don't know - when I google E. quadricostatus, most of the photos show a leaf that starts off as a narrow stem, then broaden out quite a lot before narrowing back to a point; whereas photos of...
Maybe I've missed something, but why not just refill the tank slowly with cold water so that the aquarium heater(s) can maintain the temperature within a couple of degrees of their set temp?
It does look like dwarf sag.
I'll have to look into mineralised soil (to be honest, not sure what it is).
I've used composted manure and potting mix topped with sand in another tank, and that seems to work fine, although I've run that as a low-light tank, so plant growth has been fairly modest...
Jannika, hope you get it sorted out.
Best solution other than more space is breaking up the space in the aquarium with wood etc. so they see each other less and can define their own little territories.
Not Blyxa!
Thanks so much for the replies, guys.
londonloco, seeing those photos has jogged my memory - I think I have had that plant before, and what I have now is not it.
Here are some photos - they are not very good, I know.
I've been experimenting in this tank with inserting small...
Another problem with releasing fish into the wild, even if they were wild caught originally, is that you may be introducing them into an area where the don't occur naturally; if they survive and breed they may damage the local ecosystem and put native species at risk.
