one of my 2 6” gar died suddenly, please help

  • We are currently upgrading MFK. thanks! -neo
oh **** i just changed filters, is this the reason why?
What type of filter are you using? Over time beneficial nitrifying bacteria will establish itself in the filter, on ornaments, substrate, and also on aquarium.
Changing out the cartridge is fine but the bio media shouldn't be removed for now until cycle is complete.

just normal fiber filters. yea thats why i try to keep as much as the original water as possible. is there any possible cause to my gators death
 
Original water won't help. Water has to be filtered and changed. Media containing beneficial bacteria will help. Again, learn about the nitrogen cycle!
wont all fish die if the ammonia spiked?
 
I think there is a good chance that all your fish will die. That is, if you are not pretending ignorance. [ expurgated ]
yes but all of my other fish is still very healthy as well. this is why im so confused
