Why the fuck do these fuckers keep fucking dying. I bought ten, and all but three have died. I've seen one body, and the most aggressive thing in my tank is a pair of angelfish. I checked all water chemical levels and they're perfect.
Neons are extremely sensitive to temperature changes, moreso than most other tetras. If you don't acclimate them well, they drop like flies.
>>276020ITT cardinals not neons.
um, why did you put anything tiny in with angelfish? dumbass.
Kill the angelfish and see if any more tetras die.
Angelfish eat small tetras in the wild. Also, breeding pairs of angels will become very aggressive (although they swim really slow and can't do much damage to larger fish).
