Pregnant fish may appear rounder or have a swollen belly. You can tell if a fish is expecting offspring by observing its enlarged abdomen and possibly seeing small, developing eggs inside.
A pregnant platy fish will have a noticeably swollen belly, often appearing rounder and larger than usual. You may also see a dark spot near the fish's anal fin, which is the gravid spot where the developing babies are visible. Additionally, a pregnant platy fish may exhibit changes in behavior, such as increased hiding or aggression towards other fish.
I am not aware of any "schooling" or "shoaling" fish that is not an egg layer. This would imply that these species of fish do not get pregnant.
Well some of them may change their behavior is just because they start to give birth and they may look like they are diyng, but don't worry about that, it will go away after a while.

As new born elephants weigh the same as a Ford Focus, it is quite easy for the mother elephant to realise she is expecting. If she feels like she weighs anything above what a citroen berlingo weighs, she knows she is having twins.
frogs don't get pregnant! They produce eggs.. Like fish do

It depends. Like it talks about networking, and astronomy, and something about the animal kingdom in the definition... but it doesn't talk anything about a pregnant fish.
The jelly-like substance is likely fish eggs that the pregnant fish has released. These eggs are fertilized by the male fish and will hatch into baby fish if conditions are right. It is important to provide a safe environment for the eggs to develop if you want to raise the fry.
To determine if your fish is pregnant, look for signs such as a swollen abdomen, changes in behavior like increased hiding or aggression, and a dark spot near the fish's anal vent. Additionally, you may notice the fish's scales appearing raised or separated. If you observe these signs, it is likely that your fish is pregnant.
Most fish do not get pregnant in the sense of that of mammals, like humans. They produce eggs externally and then the males fertilize the eggs. Some types, such as sharks, do get fertilized internally.
Only live bearing fish get pregnant and Glo fish being a type of danio are egg layers therefore the eggs are fertilized and develop outside the fish's body. So no Glo fish is ever going to get pregnant
it would look fat or over wait.
