he is only 2 inches and live on his own in a 250 liter tank . at the moment I am building a bigger tank but I do not wish to put him in a very large tank which I coluldnt see him

mussels , prwans swall ones, smll live crayfish 3cm , and ramshorn snails
50% weakly

this is his first tank whic in my optinion he is quite confortable

the tank was cycled fr about 3 weaks and with loads of live bacteria

and yes it seems like the bluish iridescence but what that means is the puffer stressed or something ?

and as you told me it that blue

No, I don't think it means the puffer is stressed, at least from what I've seen myself and read. I think it's pretty much normal, and common.

I already moved your thread on this into this forum. You didn't have to start a new one. Since Dad locked the other one, I left this for answers to your Q.

so I do not have to worry about it ? is it uncomfortable for him?, what I can do ?

Sorry if I haven't been clear, but I've been trying to tell you that it's nothing to worry about.

It is the reflection of light off the puffer's eye that you are seeing. There's nothing wrong. It's nice that you are so concerned about your fishy friend though.
