Filial cannibalism is a result of a spill-over response prompted by stress factors, which enhances the self-preservation instinct of fish. This isn’t a satisfactory explanation because the same behavior can be observed in fish that aren’t kept in captivity. In a study published in the Proceedings of the Royal Society B, researchers from the University of California, Santa Barbara, and the National Oceanic and Atmospheric Administration (NOAA) investigated the effects of stress on fish behavior.
They found that fish exposed to stressful conditions were more likely to cannibalize each other than those that weren’t. The results suggest that stress may be a key factor in this behavior, but it’s not the only one. Other factors may also play a role, such as the amount of food available to the fish, the size of their tank, or the type of tank they’re in.

What fish eats its own babies?
Male blenny fish sometimes eat their babies if they think they’re not worth the effort and want a better batch. The barred-chin blenny, a fish found in Asia, has an unusual parenting strategy. If she doesn’t hear from them for a few days, she’ll take them to a nearby pond. When she does hear back from her fish, it’s a sign that she’s ready to give birth again.
But if she hears nothing for days or weeks, then she knows something isn’t right. She’ll go back into the pond to look for her baby, and when she finds him, he’ll be dead. It’s not uncommon for this to happen several times in a row. This is called a “dead baby syndrome,” and it can be fatal if left untreated.
How do I stop my fish from eating their babies?
While the baby is being delivered, keep them in a smaller aquarium and separate the newborn fry. The fry will instantly get a safe place to live in if the aquarium is set up in advance. This will ensure that they get all the nutrients they need to grow and thrive. You can also feed them at night, when they are less active.
Do fish protect their babies?
Some species, such as the black-crowned night heron, have been known to keep their eggs in their nests for up to a year after hatching.
How many guppy fry will survive?
The survival rate is not always constant. It can change depending on conditions and factors. The average rate of survival in an aquarium is less than 10% of the total number of fish in the aquarium. However, in some cases, it can be as high as 50% or even higher. This is due to the fact that some fish are more susceptible to disease than others.
For example, some species of cichlids, such as guppies, are prone to bacterial infections, while others are not. In addition to this, certain fish may not be able to tolerate certain types of water conditions, which can lead to lower survival rates. The most important of these factors is the fish’s diet.
Fish that are fed a high-protein, low-carbohydrate diet tend to be healthier than fish fed the same diet but with a lower protein, higher carbohydrate content. Another important factor to consider is water quality.
Do goldfish parents eat their babies?
In some cases, the animal might not have what’s known as kin recognition and the parent might eat its offspring by mistake. In a study published in the Journal of Experimental Biology, a team of researchers from the University of California, Davis, looked at the behavior of two species of fish that are known to eat each other.
In the first case, they found that the fish would eat their own offspring if they were hungry, but they would not eat the offspring of another fish if the other fish was not hungry. The second case involved the same fish but this time the two fish were separated by a barrier.
When the barrier was removed, both fish started eating their offspring, even though they didn’t know which one was the sibling of the one that was being eaten.
Does Molly fish eat their own babies?
Cannibalism is normal with mollies and other livebearers like guppies and platys. You don’t need to worry about saving them because they are fecund. If you do want to save them, it’s best to keep them in a cool, dark place, away from direct sunlight.
If you can’t find a place that’s cool and dark, try keeping them inside a plastic bag in the refrigerator for a couple of days. This will help keep the bacteria at bay, but it won’t kill them completely.
