How Can You Stop Neon Tetra To Not Eat Guppy Fry?

To be honest, you can’t stop the neon tetra and make them not eat guppy fry. Sorry, my friend but if the guppies breed in the same tank as neon tetra, then there is a very low chance of survival for both eggs and fry.

You may be able to save the eggs using various substrates, decorations like spawning mop, plastic grate, etc.

But when it comes to guppy fry which will apparently swim around in the tank, the chance is pretty thin.

Guppy fry will come across neon tetra once in a while when they are in the same tank. And, neon tetra will eat the guppy fry without knowing the damage it is doing.

However, if you really want to save your guppy fry and make the neon tetra quit eating them, you can do few things.

Separate The Breeding Pair Of Guppies

You need to move and transfer the guppies breeding pair away from the community tank with neon tetra.

The best way to save the guppy fry is to not let them be born in the community tank where neon tetra can eat them.

You can add the guppy fry back when they are strong enough to protect themselves from neon tetra or any other fish.

Separate The Neon Tetra And Parent Guppies From The Guppy Fry

If you start to see the guppy fry in the tank and you miss the whole breeding process, don’t panic. See you guppy fry are already adapted to the water present in that aquarium.

So, you cannot risk transferring them into a new tank. Guppy fry will be very fragile and sensitive to changes when they are still young.

Neon tetra will not have to eat guppy fry to kill them, the change of environment will do. Hence, you need to look for the alternative as transferring the guppy fry is out of question and context.

So, you can transfer the bigger and adult fish to the next tank till the guppy fry grow big enough to defend themselves.

This process can be risky and hard to do but it will be your only window to save the guppy fry. This way neon tetra will not be able to feed on the guppy fry.

And guppy fry will grow freely in the tank with no stress from the presence of bigger fish.
