Request Help -- lost 1 zebra danio, now a second not eating and always hiding. Do they hurt eachother? The smallest one died, now the next smallest seems to be acting weird. The others are quite a bit bigger.
Tank size: 10 gallons

don't have kit - test at fish store...it was fine on last week's check...
tank temp: 74 degrees
Fish Symptoms (include full description including lesion, color, location, fish behavior):
zebra danio died last week (our first loss!)...it was lying on the bottom, barely moving, looked almost bent in half. It was the smalles of 6 danios. This week, second smallest danio has started hiding in the cave. Won't come out when fed.
Volume and Frequency of water changes: weekly 10% changes, last week was our first 25% change
Chemical Additives or Media in your tank: water conditioner
Tank inhabitants: 5 zebra danios (lost 6th last week), 3 platy
Recent additions to your tank (living or decoration): added 2 of the zebra danios about 2 weeks ago to complete their school...now it seems that they are headed back to 4! I added 2 more danios to the original 4 because the biggest ones were chasing the smaller and two had started hiding. I'd read that their school was probably too small. So I added two more. They did great for a few days (the smaller ones immediately stopped hiding), but then one died, now a second is hiding again.
Exposure to chemicals: my son dropped in one tiny gray rock about 2 days before the fish died, but other than that, nothing new.
