As you know, guppies are a widespread tropical freshwater fish type. They are attractive, vibrant creatures. Guppies can live for three to five years on average. However, many have had their guppies die unexpectedly. ‘Why my guppies are dying?’ they enquire.
Guppies die due to stress, poor water quality and diseases. Genetically weaker guppies also can die suddenly.
1. Stress: Why My Guppies Are Dying?
You might be surprised to hear that stress is the leading cause of guppy’s death—when they are stressed, their respiration, heart rate and blood pressure all rise. Long-term stress is one of the leading causes of poor immunity. Poor immunity is not good for fish; pathogens make them sick frequently. What causes them to be stressed? Several factors make fish stressed.
Some people had their fish die soon after placing them in their aquarium. For fish, transportation can be a nightmare at times. Tropical fish may travel long distances, sometimes by plane. They’re exhausted and scared of loud noises and physical hazards.
You purchase them after they have settled into the pet shop. They travel again to a different environment and meet different water quality parameters. Sometimes it can be too much for some guppies. They get confused and scared; incidents become vast when you are a newbie.
Transport must do with caution and as smoothly as possible.
Guppies get stressed by aggressive neighbors (guramis, bettas, large fish). They can be damaged or injured by aggressive fish. Keep a close eye on the neighbors. (platies, mollies, tetras, catfish, and plecos are peaceful with guppies) That is unless it is a deathly fact. However, providing hiding spaces is a viable option.
Breeding (while chasing)
Male guppies chase the females during their spawning season. Chasing causes increased stress on female guppies. Unless the female can die, make sure to put the correct male-to-female ratio.
2. Water Quality Variations: Why My Guppies Are Dying?
My guppies are dying due to poor water quality. Even though guppies are hardy fish, they should have well-maintained water quality.
The temperature of the water
Guppies are tropical fish that require a constant water temperature. They can withstand a temperature range of 23 to 27 degrees. As they dislike being in extremely cold or hot water, they become anxious and ill. A sudden temperature change can be fatal to your guppies. (Within some hours)
An aquarium heater is essential for guppies to regulate the water temperature. Before putting any fish in the water, make sure it’s warm enough.
Inspect the heater for proper operation and take a water temperature reading. Check the water temperature regularly after adding the fish.
Make sure that the heater you purchase is the correct size. Place the heater in a precise location to ensure even heat distribution. Towards this page, you may learn further about aquarium heater placement.
Guppies can live in a pH range of 6.9 to 7.8. They are, however, favored in alkaline rather than acidic environments. Keep them at a pH of 7 or higher to ensure their safety. First, make a note of the pH of your water supply. If there’s an error in pH, fix it. You can use water conditioners or crushed corals.
Ammonia, Nitrate and Nitrite
Fish get harmed by ammonia. It has an impact on a variety of physiological systems, including neurons. Ammonia can throw fish into a coma or perhaps kill them. In a healthy aquarium, ammonia levels should be 0 ppm.
Ammonia is generated during the digestion of fish waste, as you may know. Ammonia is converted to nitrate by beneficial bacteria. As nitrate is also hazardous to fish, it should keep nitrate to a minimum in a healthy aquarium. However, beneficial bacteria convert nitrate to nitrite, which is less poisonous.
Measure and record nitrogenous components on a regular schedule. Cycle your fish tank correctly before adding guppies.
Chlorine and chloramine
In tap water, chlorine and chloramine are present. Some newbies put their newly purchased fish in untreated tap water. Chlorine and its components are deathly toxic to fish. Use a de-chlorinator to get rid of it.
3. Weaker Genes
You may have seen some stunningly attractive guppies in aquariums, but they are not seen in the wild. Who are they, exactly? They’re inbred guppies. When breeders discover significant factors in a guppy fish, they continuously try to create these valuable guppies. They do this by mating closely related guppies repeatedly (Inbreeding).
Even if they are attractive, inbred generations are weaker than usual. They have a limited growth rate and fecundity and can’t survive in changing environments.
Guppies are hardy fish, but they die due to unclear reasons—a few possible reasons for the sudden death of guppies. First is stress; due to traveling, fighting neighbors or spawning seasons. Poor water quality is another deathly fact for guppies. With that, genetically weak guppies might die without any showing reasons.
