Tips For Helping Fish Without A Tail
1. Separate the Fish
It’s recommended to separate a fish that has lost its tail.
This is more to ensure it has full access to the resources being given to it. For example, you will want to pour food into the fish tank to expedite the fish’s healing process.
However, if there are other living organisms in the fish tank, they are going to go after the food and likely win the battle too.
This is something you want to avoid with an unhealthy or injured fish in the fish tank. By taking the time to separate the fish, it is a lot easier to ensure it does get access to those all-important resources when it is injured.
Fish will commonly get hungrier when they are recovering. This is to make sure they have access to the key nutrients that are needed to promote fin or tail regrowth in fish.
If there are issues in the resources you give to the fish, it will go through the recovery phase much slower.
The best course of action is to simply separate the injured fish, let it swim somewhere else, and then reintroduce it into the main fish tank once the tail is back.

2. Keep Feeding the Fish
Feeding the fish is essential during the recovery process.
The goal is to give the fish enough food for it to recover. If the fish isn’t getting enough nutrients during the day, it will have a much tougher time getting better. This tends to apply to any health-related issue for fish.
You will want to keep tabs on how much the fish is eating and ensure it is being well-fed at all times of the day.
Making a strict schedule during this phase does go a long way.
It will lead to better results and is also going to allow the fish to focus on recuperating.
3. Increase the Frequency of Water Changes
How often are you changing the water in the fish tank?
The goal is to continue increasing the frequency of the water changes. This means not changing the water once in a while as the fish recovers.
Look to change it every other day during this period.
The idea is to make sure the water condition is at 100% at all times. You don’t want the fish to have to overcome environmental hurdles when it is already weakened. This is even more important if you only have one fish in a smaller fish tank.

4. Be Patient
You have to realize a fish that doesn’t have a tail will need time.
The tail is not going to regrow in a few seconds. There will be a waiting period that can go into weeks or months depending on the size of the fish.
This recovery process is something you should expect as soon as the process begins.
As long as you are keeping the fish well-fed and the water quality is healthy, everything should work out as you want it to.
This is what your priority should be as a fish owner during this troubling period.
Final Thoughts
Can a fish survive without a tail?
A fish can survive without a tail whether it’s in the wild or fish tank. The goal should be to let the fish an opportunity to recuperate by changing the water regularly, giving it enough fish food, and making sure it is not threatened by other organisms. This will ensure the tail regrows at a fast pace.
Take the time to look into this and make sure things are done patiently.
The recovery phase will work out as long as you are methodical about your approach.
