Although Neon Tetras prefer to live in a school of their own kind, they will still nip on the fins of other Neon Tetras.

Fin nipping can be a natural behavior of Neon Tetras as they sometimes use fin nipping as a form of expression or to sort of introduce themselves to other fish in the tank. 

However, there are also reasons such as overcrowding in tanks that may cause the Neons to nip fins, and also if a male Tetra would like to mate with another female, they would nip at the fins of other male Tetras.

Claim for territory is another reason Tetras will nip at other fishes as they send a warning to other fish who may threaten it.

What to do with Neon Tetras that nip fins of other fish?

You may be surprised once you see your other fish with nipped fins nips, and the culprit is your Neon Tetra. There are types of fish that are not suitable to be together, and this is what you need to research before setting up your aquarium.

If you are having a problem with a Neon Tetra that has been creating havoc in your fish tank, leaving some occupants with frayed fins, it must be the time to act on it. Some things you can do to keep the fin-nippers from creating further damage to your fish tank are as follows.

Observing the Neon Tetra fin nipper

First, know whether the fin nipping is normal behavior, and the Neon Tetra that is doing the deed is not just being playful with other fish in the tank. Neon Tetras love to chase and nip at other fish, even their own kind. Sometimes this is their form of introduction to the newly introduced fishes.

If you notice that it is no longer a playful display and it is causing stress to the other fish in the tank, you need to act on it.

You may need to examine what is causing it to become aggressive. You may have added a new type of fish to the mix, not knowing that your Neon Tetra is feeling threatened. Check if the fin nipper is often in hiding and if it is joining the other fish.

Frequent hiding may mean that the Neon Tetra feels their territory is being threatened and do not want to leave the spot.

Adding additional hiding spots will help to have darting space for all the fishes in the tank, and if the fin nipper is eyeing another fish, there are spaces to hide for the bullied fish.

Provide a larger fish tank

Once you’ve noticed your Neon Tetras having fin nipping issues, maybe it is time to furnish a larger fish tank. A bigger tank can help your Neon Tetras, and other fish in the tank move freely, and they can swim comfortably as there is a bigger space to move around.

Problems are lesser compared to smaller aquariums.

Remove the offending Tetra

No matter how you many methods you try, such as plants and decorations inside the tank so there is a hiding place for the other fish, a highly aggressive Neon Tetra will not stop. This is true, even if it is not mating season or the fish has all the ideal requirements for all the fish to live peacefully, and there is enough feeding, the fin nipping and harassment to other fish may very well continue.

The other fish will get stressed and suffer because of the constant nipping and attacks that can lead to death for the other occupant of the fish tank.

What you can do in this situation is remove the offending neon to a separate tank if you have one or you could try to find another owner that can take care of the fin nipper or if someone is willing to house the fin nipper in a separate tank.

You can also return the fish to the pet shop where you bought it and let them know why you have to decide on it. Although this is the last resort, you may need it if there is no other fallback.
