Walminski, you've got no chance of a long and healthy life if the greens are those artificial fronds you get in tanks, it'd be the fishy equivalent of a KFC bucket.
Oh Tricky, absolutely not! I like neon tetras, I just got a bit carried away with the novelty of having a psychotic fish named after me! Though I do hear it's a dog eat dog world in that tank (or the fishy equivalent) so if I was you, my new motto would be carpe diem... ;-)
