3 of my guppies died last night, why?

Question

2 of them were male and 1 was female, they were swimming around fine when i went to sleep last night but now there dead? will the rest of my fish die? i have only 5 guppies now :(

Answer 1

maybe they reached their max life span. My guppies drop dead when they reach 1 and a half years.

Answer 2

It could be alot of reason, but the other thing I can think of is not enough oxygen..? Or was something put in the water?

Answer 3

Test your water with a "quick dip" test strip.  Your Ammonia or Nitrites may be high, which are toxic to fish.  You may need to change part of the water.

How long has your aquarium been set up?

Answer 4

Do you have a heater? Check that it is still working and that the water hasn't got too cold.

Answer 5

Guppies are notorious for dropping dead, though it's weird that three went at once. Could just be coincidence.

Female guppies can die of stress if they are constantly persued by males, it's always better to get a higher ratio of females to males.

Answer 6

what size tank?

Test the amonia and nitrate and PH.

Ph for guppies should be 7.0-7.5

Temp from 75-84(f)

If the amonia nitrate are high do a 50% water change.  If the PH is  high or low then change it slowly...

Answer 7

if they are goldfish then that means that you were not cleaning and filtering their cage well enough, goldfish are very high maintenance.

Answer 8

u may have a bacteria problem in yr water your best bet is to do a 30% water change de-chlorine the water too this will help just incase there is an infection in your fish ,u can get an internal bacteria treatment for your fish just incase but best to do water change first plus also yr ammonia levels will be up now due to deaths of fish in your water

hope this helps and good luck  

Answer 9

uhh i can think of a few reasons, either there was a disease and you couldnt see it, but you could have seen it from observing the fish, also probably suffered from lack of oxygen if you dont have a filter or bubbler. also same thing with filter probably no filter and dided from its own c**p. evacuate other guppy to another location and clean tank fully. you can ask me anything just message me, id be glad to help.
