Hi all I can a Puffer fish (poison type)
And he has been acting very weak the last 4 days, i have only had him for around 6 days now.
He is in his own tank. and has been feed live fresh water barbs.
I noticed the tank was a bit warm then normal as a i think the heater is playing up (sitting at 27deg)
and not 24, He hits the side of the tank alot like he is blind and just floats around and gets pushed by the water pump..

Im a bit worried with him as it doesnt look like he will last much longer.

salt lever is .023, I have done a 50% water change, the tank is strong and about 6 months old.


Can anyone help me out?
thank you
