Ok guys, I'm baffled now.
Went away on vacation. While I was away, the cycle completed. Had a few nitrates (<5 ppm), and zero ammonia and nitrites. Did a recheck of 4 ppm ammonia - cycled in 24 hours. Did a 90% PWC and all according to the guide looked good.
So stocked lightly with 6 zebra danios and 10 ghost shrimp. The shrimp have done ok, but 3 of the 6 danios are dead, and a 4th is looking weak. Ammonia and nitrites still read 0 (just checked again).
Ideas on what's up here?
