Neons or cardinals?

[lgreenmk]

How are they doing now? I have six neons total, and have hard water as well. They were doing fine already, but now I am doing water changes with distilled water and that seems to help the water hardness. I just started doing that, so we shall see how (if at all) it affects the neons.

Out of the six I got last night one seems to have disappeared.

Also, check the floor and under furniture.
If they jump out, they can go a LONG way before subsiding
