The Puffer Forum

Hi guys, I just got two green spotted pufferfish yesterday. I prepared brackish water, the temperature is ok. I gave them clams, they didn't eat much but they seem to be ok at the beginning.
But later last night, one puffer started floating on the surface, not moving at all, not even when I touch it. Initially I thought it was because of the lack of oxygen so I put the pump into the water and after a while the puffer returned to normal. But this morning, it turned to this again. I'm not sure if it is just sleeping or there's some serious issues.
The other puffer looks ok. It is swimming around and sometimes it looks like it is having a nap. But when I approach it, it sees me immediately, turns to be active and swims. But the other puffer is not like this. It is not moving much even when I touch it. Please could anyone tell me what's going on with the puffer that is not moving? Is it dying? What can I do? Many thanks!!!

He's either dying or has air stuck in him. Please answer ALL the questions above, in red.

hello
i think u put to much salt on water, if u dont take time to aclimate the puffer to the salty water he will float…

i had green spoted puffer before, the one who lives longer was the one that i put in full salt water with corals, during the aclimation, some of them start to float just like yours, i had to get a step back and put fresh water again, and then slowly put more salty water, some fishes aclimate very fast, other not really, try to put fresh water and then slowly mixed salt water again, it takes time, but when u put them in full salt water all the problems go away (parasites etc)

u bought the fish 2 days ago, almoust 100% sure that he was on fresh water, so u have to go slowly with the salt

hope i help u
