Yes, guppies will eat their young. This is why you should separate the guppy fry from their parents and any other fish if you want to save the babies.
Male guppies have color in their tails,females never have color.
Fish do not care for their young. Some even eat them.
Dandelion dragons are hard to make: plant a dandelion and put a fish scale in together, thats it! but fish scale must be a tuna fish scale or gupy scale(soooo small)
They mainly eat fish as adults. The young too eat fish but also invertabraes
Insects and small fish.
Piranhas eat fish, frogs, toads, turtles, young anacondas, young caimans, and birds.
they eat tropial baby food
Tigerfish eat fish, reptiles, birds, and young crocodiles.
Highly recommend separating the adult fish from the newborn fry or you are likely to see the larger fish eat the young, even the parents of livebearers will eat their young.
Young children can eat fish, if there is no bones there.
If you're trying to feed your own small fish, usually crushed fish flakes, or crushed bloodworms will do the trick. In the wild, young fish's diets can vary wildly, as these species are much more varied. Sometimes what qualifies as a 'young' fish in some species are still big enough to eat smaller fish.
