A pregnant Jack Dempsey fish typically exhibits a noticeably rounded and swollen abdomen, signaling the presence of developing eggs. The coloration may also become more vibrant, with the fish displaying deeper hues of blue, green, or gray. Additionally, the fins may appear slightly more pronounced as the fish prepares for breeding. Overall, these visual changes help indicate that the fish is in a breeding condition.
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.
A "jack salmon" is actually a pike like Perch fish, not a salmon at all
Yes. Most tropical fish are carnivorous. Even a guppy is carnivorous. If you are referring to fish like Piranha, then only certain species are allowed to be kept in the U.S.A. Southern states, places that Piranha and other Amazonian carnivorous fish may thrive, they can not be purchased.
Oscars are tough buggers and get pretty big the only thing that could kill a full grown Oscar is age or you. If you want to get rid of it which hopefully this is not why you asked the question just call a small chain or family owned pet store they will usually take it.

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.
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.
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.
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.
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.
