That depends upon the species of fish. Some can breed every 3 weeks and others only breed once in their lives.
Fish in aquariums eat fish food found in any pet or fish store. Fish in the wild mostly eat smaller fish and small particles in the water. Some types of fish living in aquariums also eat smaller fish. Often, fish will eat their own babies so aquarium owners know they must move babies to a smaller fish bowl or tank to protect the babies from the adults.
Flying fish reproduce by eggs, and eventually, babies make babies and more babies to form a family. Most fish do, anyway
Fish don't even have babies. Fish lay eggs, so no.
Depends on the type of fish
of course they can! usually fish have 100 babies and only 20 survive!!!!!
If there is a male and female beta fish, the male probably ate them, and those 2 unlucky babies were definitely male. (male beta fish will kill other fish.)
More likely the opposite, the crab will eat/kill your dragon fish. Plus fiddler crabs do not often reproduce in captivity.
they eat them
If the fish can find the eggs and/or babies they will eat them.
Probly depends on WHAT fish it is
Actually it depends on what kind of fish it is.
Some species of fish stay with their offspring, or babies. Most other fish will release eggs into the waters they live in, and the fish develop and grow on their own.
