Hello.
Briefly- new tank, few months old. All going well, besides 6 neon tetras dying (two found dead inside filter). Water chemistry good (though I have no ammonia test kit). The remaining population:
7 Neon Tetra
3 Black Widow Tetra
3 White Tail Tetra
2 small catfish
So... came home tonight and found only 2 black widow tetra. Took out and examined all plants, removed bog wood, removed opened and re-installed filter. Can't find fish. The black tetras are the largest fish in the aquarium, (all small fish) so it couldn't have been eaten. No idea what happened. Any ideas? I'd like to remove the dead fish but there doesn't seem to be one. What consequences are there if it's not found?
Also, my neons have a tendency to hang vertical by the filter intake. Why might they do this?
Thanks again,
G.
