All fish has their unique behaviors which they exhibit from time to time and when they do, especially those that you are not familiar with, you will be shocked.
I have read many people asking why their Pufferfish are curling or bending their tails.
Well, Pufferfish could exhibit some funny behaviors which could either be entertaining to you or keep you wondering if something is wrong with them.
If you are worried about your Puffer curling its tail, then read this article to the end.
Puffers are saltwater fish but very friendly and funny too, they could exhibit many behaviors which could be alien to you.
Talking of their funny behaviors, one of them is bending their tails which makes them look as if they are small.
They naturally do this and you have nothing to worry about.
What I meant to say is that they do it for no reason because it is one of their natural characteristics.
They do it sometimes when they sleep, when they are in a group, and sometimes when they are sick or stressed.
If yours is doing this and it is still very active and still eating voraciously, then it is not sick, just its normal behavior, so you have nothing to worry about because even if it is doing it because it is stressed, stress alone won’t kill it.
So, you have nothing to worry about when you see your Pufferfish bend its tail.
