It's been a heck of a day. A few days ago I added a golden apple snail to my 10gal tank with 2 tetras, 2 baby platys and 3 fancy guppies. Within 2 days all the guppies and platys were dead, and just today a tetra died. The guppy I was able to examine closely appears to have had ick. The snail is dead as well.
So obviously I'm close to starting over, but here's my 2 questions...
a) did the snail cause this?
b) should I completely overhaul the tank and start over, cycle it, etc? I can find a temp home for the remaining tetra in a small tank.
I'm so disappointed.
