Many people assume that fish are neglectful parents who don’t care for their young. But this belief is a myth – the reality is that some fish species demonstrate remarkable parenting skills and go to great lengths to ensure their offspring survive and thrive.
While it’s true that some fish like guppies and silver dollars provide no parental care, there are also dedicated fish parents that will vigilantly stand guard over their nests. Some fish take parental care to such an extreme level that they carry fries around inside their mouth. These fish are called mouth brooders.
With an understanding of these parental fish types, aquarists can better support breeding and avoid mistakenly separating caring parents from vulnerable offspring.
Do Fish Take Care of Their Young?
Well, the answer might surprise you. Some fish indeed look after their young ones, while others might see them as a quick snack.
Certain fish species, like the mouth breeders, go to great lengths to protect their offspring. These dedicated moms carry their babies in their mouths until they’re old enough to venture out on their own.
However, not all fish are as nurturing. Some species lay their eggs and swim away, leaving the young ones to fend for themselves. In fact, in certain cases, the young fish might become a tasty meal for other fish or even their own parents. It’s a tough world out there in the underwater realm, where survival often depends on instinct and luck.
So, to answer the question, yes, some fish do take care of their young, showing remarkable parental instincts. From protecting them in their mouths to creating safe spaces, fish parenting comes in various forms. Yet, for others, the young ones must navigate the waters alone from the very beginning, facing challenges that shape their survival instincts from day one.

Caring for Fry of Parental Fish
When keeping fish species known to care for their young, there are essential steps aquarists can take to ensure the successful raising of fry into adulthood. Providing the right environment and support can significantly enhance the survival rate of the offspring:
1. Leave parents with eggs/fry undisturbed in the main tank
When fish parents have eggs or newly hatched babies (called fry), it’s important not to disturb them by moving them to a different tank or separating them from their home.
For fish, moving them can cause a lot of stress. This stress can make the parents forget about their babies or even decide to eat them! It’s like if someone took away a parent’s babies—they might get worried and not know what to do.
So, by leaving the fish parents and their babies alone in their main tank, we help them feel safe and comfortable. This way, they can focus on taking care of their little ones without any worries.
2. Remove tankmates that may prey on eggs/fry
Sometimes, other fish in the tank might want to eat the eggs or baby fish (fry). Just like how some big animals might eat smaller ones in the wild, certain fish in the tank, like gouramis and tetras, might see the tiny fry as snacks.
To keep the baby fish safe, it’s important to remove these potential “bad guys” from the tank. By taking out the fish that might eat the fry, we create a safer environment for the baby fish to grow up peacefully.
This way, the parents can relax knowing that their babies are protected, and the fry can grow up without any big fish trying to eat them for lunch!
3. Provide hiding spots
Just like how kids like to hide in forts or behind trees during games, baby fish (fry) also need hiding spots to feel safe.
In the fish tank, it’s important to have lots of plants, caves made of rocks, or pieces of driftwood where the baby fish can hide. These hiding spots help the fry escape from other fish that might be a bit too pushy or even want to eat them!
Having lots of hiding places makes the tank feel like a safe and cozy home for the baby fish. It’s like having your own secret hideout where you can go whenever you want to feel safe and protected.
4. Feed small foods
Just like how parents give their kids food that’s the right size for them, fish parents also need to feed their baby fish (fry) tiny meals.
For baby fish, it’s important to provide small and easy-to-eat meals, like tiny particles called infusoria, powdered flakes, or small brine shrimp. These foods are like little snacks that the baby fish can munch on. The parents show the fry how to eat by demonstrating, just like how your parents might teach you how to use a fork or spoon.
Feeding the baby fish the right-sized food helps them grow big and strong. It’s like making sure they have the perfect meals that match their size, just like how you have meals that are just right for you!
5. Maintain clean, warm water
Ensuring a clean and warm environment is crucial for the well-being of baby fish, known as fry. These little fish are sensitive, and dirty water or sudden temperature changes can be harmful to them.
To keep the fry healthy, it’s important to regularly change some of the water in their tank. This helps remove waste and keeps the water fresh, creating a comfortable living space. Think of it like cleaning your room to make it a pleasant and safe place to be.
In addition to cleanliness, maintaining a stable and warm temperature is essential. Aquarists use devices like heaters to regulate the water temperature. Consistent warmth is like providing the fry with a cozy and stable environment, preventing them from getting too cold.
6. Avoid overcrowding the tank
Imagine if you had to live in a tiny room with lots of other people—it would feel crowded and uncomfortable, right? Well, fish can feel the same way if there are too many of them in a small tank!
It’s important to make sure there’s enough space in the tank for all the fish to swim around comfortably. When the tank is crowded, it can make the fish feel stressed and upset. Just like how you might feel cranky if you don’t have enough space to move around, fish can become grumpy too!
By giving the fish enough room to spread out, it helps them feel happier and less stressed. Plus, when there’s plenty of space, the parents can watch over their babies more easily and make sure they’re safe.
Conclusion
I think I have discussed most, if not all, of the common fishes that. As a fish-keeper, you might stumble upon one day. After reading this, you will surely not be mistaken whether your fish is attacking the fries or protecting it. Also, the fries of the fish that I have mentioned above don’t require much care as their parents look after them.
You should just make sure that there are no threats from bigger animals, and the temperature is a bit warmer than usual. Therefore, I suggest you go through this article one more time and know about how different kinds of fish care for their young ones.
