I got a dozen neon tetras the other day from lfs. As i was there, a young member of staff was doing maintenance on all tanks at once, including a 20% water change. As he bagged the neons for me, one went belly up and he replaced it. Should've stopped there but I was optimistic. For some reason I thought most tetras are hardy. One more died on the way home (less than 20) minutes. One more died before nightfall. 4 more had died by morning yesterday. Picked out 3 more corpses this morning. One corpse was lost to snails, shrimp etc.I only have peaceful fish right now, including some black neons that have been doing well for a long time. My pH is 7.6 and I have hard London water. 25-26C temp and rather high nitrates at about 60ppm (50out of the tap). Do you think they were shocked from the shop or is it also due to my water?
