find dead fish without previous symptoms.
Changing the filter or a recent plant pruning could have slowed down plant
growth enough to create an oxygen problem.>>>>>>
This is a good question, and I should have mentioned in my original post,
that I do not run CO2 on my tank (not brave enough, yet!). Also, I did not
notice any fish gasping near the surface, or seeming uncomfortable.
Someone at the LFS was speculating, that perhaps my three Black Skirt Tetra
are getting rambunctious with the other fish. They are becoming quite
large. I haven't ever SEEN them harrassing their tankmates, but who knows
what they do at night? These are fish that were given to me, and I am
thinking of trading them in anyway. Does anyone know if Black Skirt Tetras
could be nasty enough to cause death of tankmates?
