thanks for all the replies! i'm not really looking to stock my tank right now. i was asking more out of curiosity b/c i've had neon tetras in the past and they don't seem to be the hardiest of fish. i currently have albino buenos aires tetras and they seem very hardy.
I couldn't keep NT's alive, but... I got 6 Tin foil Tetras, and they have thrived to the point that a few of them are as big as my hand. It's crazy! Their appetites are voracious. A friend came over and said, "I like your Angel fish".
I didn't bother to tell her they were tetras, I didn't figure she'd believe me anyway. :look:
