Your female guppy is getting close to delivery time when the she is very large and has a boxy appearance. It takes about a month for the fry to be ready for birth.
You can tell that your guppy is very close to having the babies when you can see little dots (the baby guppies’ eyes) in the gravid spot.
This process may repeat itself many times during labor – tightening muscles, then becoming more relaxed.
Mating can occur very quickly and often happens without the owners even noticing.
Shaking or shivering Rubbing itself up against things in the tank – the wall, leaves, decorations Refusal to eat
A guppy in labor may also try to hide from view or display certain aggressive behaviors like fin nipping.
A stressful environment can harm the unborn baby guppies and ruin their chances for survival.
Breeding boxes, or net breeders, are a little chamber that hangs or sticks on the inside of your tank to isolate sick fish, aggressive fish, pregnant fish, and fry. Breeding boxes are quite inexpensive and usually last through many uses. It’s a great investment for something that can save the life of your guppy and her fry. You want to keep the pregnant female in the breeding box for as little time as possible to minimize stress. So watch for symptoms of labor and put her in the breeding box when she is close to having the fry. If the guppy has been in the breeding box for 24 hours and hasn’t given birth, let her back into the main tank. Try slightly increasing the temperature of the water, which can help the birthing process. To get the guppy in the breeding box, you can use a fishnet and gently transfer her into the breeding box.
Try alternating days between regular flake food, tiny fish food pellets, algae discs, krill, bloodworms, or brine shrimp.
Having a lot of babies means eventually they’ll need a larger tank, for each of them will become around 2 inches (5. 1 cm) long and a tank cannot be overcrowded. When tanks are overcrowded, it creates tons of stress. This can even cause the adult guppies to eat their babies.
Many fish can get Ich, a rot that forms on their tails, bodies, and mouth that can kill small fish in as quickly as 24 hours, while it may take a few days to begin affecting larger fish. To help kill bacteria that cause diseases like Ich, get an Ich/Disease treatment to put in the water. For prevention, aquarium salt applied as instructions say will kill parasites.
