Embryo's have gills to breathe inside placenta.
It's at the bottom of the tank, not floating, and I'm pretty sure it's breathing. It's sort of buried in the gravel, and I can't tell if she's having babies or the other fish had a memorial service and then buried her lol!
Flying fish reproduce by eggs, and eventually, babies make babies and more babies to form a family. Most fish do, anyway
To determine if your fish is sleeping or dead, observe its breathing and movement. If the fish is still breathing and shows some movement, it is likely sleeping. However, if there is no movement and the fish is not breathing, it may be dead.
Fish breath underwater
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.)
As the temperature changed, the fish's breathing rate increased or decreased accordingly.
they eat them
If the fish can find the eggs and/or babies they will eat them.
No reptiles are air breathing, cold blooded, egg laying animals. Fish are not air breathing.
Probly depends on WHAT fish it is
