It looks good but that massive airstone won't help your plants, the plants should give off oxygen to help your fish
Hmm I would normally agree, but my plants have been fine with that airstone since the tank was set up. Also at the moment I'm medicating the tank for callamnous worms, so a bit of extra airation is more than welcome.
My future plans (once I've sorted the worm problem) is to make the dwarf neon rainbow shoal 8, make the corydora shoal 8, khulis = 8, cardinal tetra = 8
and then I might add a CO2 sytem for my plants lol.
Now I know some of you may think that, that will overstock me. But I've had the tank overstocked before and kept on top of the water changes and toxin levels without a problem and never encounter any problems with being overstock

Just means a bit of extra work, which I don't mind.
