on sunday i got a new 12" bass, and yesterday i did a feeding with silversides to the other bass. when i came home from school today, all the pbass were dead. parameters are ammonia 0 nitrites .25 nitrates 20. Did my tank mini cycle? can .25 nitrites kill all my fish in less than 24 hrs? this is the first time in 5 years that i havent had a peacock bass in my collection of fish. i have an fx5 with bio balls on the tank and 2 ac110s and a diy gravity fed filter with bioballs. the tank is a 180 and had 4 inhabitants at the time.
mass death

WOw, sorry for your lose bro. I wouldn't think a mini cycle would hit in 24 hours. What are you running filter wise?
I don't think that low of nitrites, or the ammonia that caused them, could cause a spike bad enough to kill all your bass. If it was rays or something more sensitive maybe, but bass I dont think so. What else was in hour tank? Is everything dead? If not what survived? What else has gone on in the last 24 hrs? Water changes, power outages, cleaning, etc?

just had the four peacock bass. I think i did a water change on sunday or saturday. no power outages. my arowana in a different tank in the same shed is fine and so is my miniatus grouper. i didnt even feed that heavily maybe 4 silversides? if it had been bad water that killed them, would it have been that quick?
It could be that quick if one of the bigger bass died first. In a well heated tank, a fish can and will rot a lot quicker in a colder tank. So, yes...if the bigger bass died first, then that will kill the whole tank.

Hard to say what killed your fish. Could be a number of things. The water change, the silversides, or possibly a disease brought in with the new addition to your tank. Also possible that one of the fish died and quickly polluted the water. My best guess would be the new fish came in with some type of disease. You should learn to always quarantine new fish for a couple of weeks before adding the fish to your main tank.
Joe, any fish that is introduced to a tank will not kill a tank in one night if it was carrying a parasite.
But, yes, one large or medium fish that had died can sour a tank and kill off a tank in one night or even sooner.

Don't know the the house temp in SoCal in the winter.
But my bass went to 70 degrees in the winter where I stay at. Sluggish, but still very much alive.
