So depending on cause of death it may make sense to do more
In my case today i found a neon wedged between my angels plus sponge and the side of my tank. That sponge is practically glued to side of tank with the in/outside magnets. Think be ran in there after being startled and just could not get out and I found him too late. Now the neon school only has 5
the really crazy thing is that I found 2 more wedged In there as well today... But I freed them within a few seconds. The filter is now sitting in the center of the tank needless to say as these neons are proving to frighten very easily.
