Aquarium Advice Addict
Well, I have a 10 gal tank, been cycled for over 6 weeks, with plants - anacharis, crypt, and anubia, and a small piece of driftwood. Aquaclear mini filter, temp of 78 degrees. pH of 7.6, ammonia 0, nitrite 0, nitrate between 5 and 10 ppm, probably closer to 10 (dang color charts!).
I took out my 3 danios that did seeded cycle duty 7 weeks ago, and put in 6 jumbo neon tetras about 5 days ago. Day one, one dead tetra. day three, another dead tetra. day four, another dead tetra, and day five, two dead tetras. Just one little dude left now. They were all were swimming actively and eating the day prior to going belly-up. Fed crushed flakes, and frozen baby brine shrimp on occasion. The only thing I see that is puzzling is an oily sheen on the surface of the water, don't know what it is. Thought perhaps it was a residual from Flourish added a week or so ago.
Any ideas? are the neon tetras just that touchy and sensative? I haven't tried to keep them in decades, and didn't have much luck with them back then, thought a little planted one species tank would be ideal for them.
edit: saw the sticky profile. I have the neon tetras, not the cardinal tetras.
