The Puffer Forum

I need help and fast.
I have a dog face puffer. He had white spots earlier this week. I followed directions and lowered the salt and the water is fine.
This morning he was putting his nose in the sand. I came home from work and he looked dead. I picked him up in a net and he puffed up. He is now dark brown and has a white mask around his eyes and nose.
I need help. Please help.
Thanks

Water parameters? tank size? tankmates?

What did you lower the SG from/to? In what period of time?

We need more detail....do you have a water testing kit?
