The guppy fry are born with their outer layer of skin still filled with yolk sac. The eggs look like frog spawn to some extent and the babies seem part tadpole too.
They stay in this state for about ten days on average, but may take anywhere between 9-15 days to hatch out entirely after which they become free swimming little fishies.
Some people think that moving newborn guppies from one tank to another is a great idea as it can lessen the chances of them being eaten by their own parents once they have hatched out, but it is not recommended because they will be more at risk of getting sucked into the filter or top-drain/filter area if you do move them into a different tank.
1. How Guppies Are Born?
Guppies have the ability to reproduce year round unlike their cousins, the mollies. Most females will even give birth to babies that are half-grown.
Guppies do not lay eggs like other fish species but instead, mothers carry her young in her womb for about three weeks after which she gives birth to babies that are close to being fully grown already. During this three week period, mommy guppy’s belly becomes noticeably swollen and may become speckled with black dots if she is carrying a large number of fry (babies). This ‘belly spot’ seems only visible on pregnant guppies due to an increase in blood circulation/concentration around the pelvic area.
During pregnancy, some female types may produce a substance known as “guppy milk” which is similar to mammalian milk in that it is produced and secreted from the female’s body for her babies’ consumption.

Contrary to popular belief, male guppies do NOT fertilize their own eggs like how normal fish species with external fertilization process have to do so (i.e. goldfish ). Therefore, they will only ever get to enjoy sex once in their life time but by doing so they may end up siring hundreds if not thousands of children!
Mothers guppies, on the other hand, produce a substance known as “guppy milk” for their babies’ consumption. It is very similar to mammalian milk but it is not produced in breasts like mammalian counterparts do. Instead, it is produced from the lining of a female’s oviduct which she uses to feed her newly hatched babies.
At first glance, fry born at early stage seem like part tadpoles with fully developed front and hind legs (fins). Later on they may develop more adult looking bodies with larger eyes and brownish body coloration which are characteristic of adult male guppies.
A few days after giving birth mothers will go back to normal so if you see pregnant guppies swimming around or on top of the water you can expect fish babies to be delivered soon. On average, most female guppies taking part in this biological process produce 4-7 eggs at one time but some may end up producing a few dozen if not more!
2. How to Save Your Guppy Fry?
If the tank is big enough and mommy has plenty of food sources, she will take care of her own young without any effort on your behalf. One thing that is absolutely necessary for new born fry is clean fresh water, so make sure to change the tank water on a daily basis in order to keep it as hygienic as possible.
When changing guppy tank water regularly and keeping good hygiene standards (i.e feeding them on a regular basis ), guppy mothers will continue to take care of their babies even if they lose track of them for a few hours and/or days.
Guppy fry are born with eyes closed therefore it is recommended that you feed newly hatched baby guppies before they open their eyes or once every 1-2 hours after they’ve opened their eyes. Newly hatched baby guppy fry don’t have teeth yet at this stage but being carnivorous in nature, they may end up eating each other alive if food isn’t supplied regularly !
If your tank has catfish then be very aware that these fish species eat any living thing that comes down the way including newborn fish babies. Therefore, if you notice these type of fish in your tank remove them immediately! You may buy some small fish such as danios or shrimps and leave them in the tank as these would be beneficial by getting rid of any unwanted pest/algae growing inside your tank.
On average, fry born 3 days ago are just about ready to consume solid food. If you haven’t got “guppy milk” supplies then you can try feeding newly hatched baby guppy fry with newly hatched brine shrimp (found at most pet stores) or crushed up flake food . Just remove the uneaten portion from their tank within 15 minutes to minimize water pollution caused by decaying organic matter.
While keeping an eye on mother’s progress it is recommended that you manually remove all deceased babies from the bottom of the tank. If the newborn fry is still alive at this moment you may place them back into their own mothers’ tanks to be re-accepted by their own mothers. If the fish baby is already dead then you can remove it from the bottom of your tank and throw it away in a garbage bag once you do not see any movement for about 15 seconds .
3. How to Feeding Guppy Fry
Although they are very small in size, a newborn guppy fry is hungry enough to eat every 30 minutes. It does not mean that you have to feed them so often but rather the more times you do it will encourage their growing speed and make sure each meal has all of its nutrients needed for healthy growth.
A newborn guppy fry only measures about 6 mm which makes their mouth seem tiny too! However, this doesn’t stop these little guys from being ravenous and making digestion cycle last just 20-30 minutes; meaning your fishy friend could be ready for another go at eating any time after half an hour passes by (though 5-10 meals per day would suffice).
It is recommended that you feed newly born fish babies 2-3 times per day; at 8:00 am, 12 noon and 4:00 pm. Once your baby guppies are 6 days old they will be more than ready to eat newly hatched baby brine shrimp .
4. Guppy Fry Tank Maintenance
If the tank where the fry was born is not big enough (which most probably is if it only contains mommy & daddy) then do not worry as these little guys love swimming around and therefore having plenty of space to move around in would be beneficial for their growing stage. However, check on them once a day to make sure their water remains clean and changes regularly or else they’ll end up getting sick & die within no time!
Another thing you need to keep in mind is that baby guppies are very susceptible to water pollution . While it’s recommended that you change the fish tank water every 3 days (i.e 25% of volume per day) throughout their growing stage, do not forget to add dechlorinator into the new batch of tap water before adding it into your tank .
It is also worth mention that babies are much more sensitive than adults and therefore if you notice something wrong with any one of them then replace all water in your tank immediately ! On a side note, if there is algae inside your tank (found at the bottom) make sure to remove it as well as these would be harmful for your fishy friend(s).
Although there are not that many other species of fish as good looking and easy going as guppy, you should still treat them with care because they’re young. Never overcrowd your aquarium and make sure to change the water regularly for a clean environment any young fish babies can grow up in!
In conclusion, if you’re an experience owner of this particular fish then please share some important facts about baby guppies? This way inexperienced hobbyist would have more information on how to look after their young ones!
