Why did all my fishes die?

Question

my fishes had been in good shae for a while nothing changed but today all 6 of them woke up dead i mean ived had other fishes die before but it was only like one and it was when i barely got them so i didnt know how to take care of them but now its been a while and theyve been healthy but their al dead and it weird why do yo think this happened?

Answer 1

we need more info

tanks size

temperature

what fish you had

ph

nitrates

ammonia

also the plural of fish is fish not fishes

unless they were all different types of fish then you can use fishes but i personally dont like people using it.

Answer 2

Did you clean the tank with any house hold chemicals because that is what probably killed them or a dramatic change in temperature.

Answer 3

you need to check the ph of the water, I bet it is way out of range...check temperature too.

Ph fluctuates very quickly especially in smaller tanks.  

Answer 4

usually its because you feed them to much or you don't feed them at all. also at first when you buy the fish put them in the tank but leave them in the bag. just let them be there for like a couple of minutes so they can get used to the water. this  might make them less shocked of the water.

hope this helps if you want to know more try contacting a pet store or where you bought the fish from ok so bye.

Answer 5

Did u clean the bowl before they died. I had 3 fish a about 20 minutes later they all died because it is a new enviroment. That is probably 99% why all your fish died or they could have breathed something bad
