Hi y'all I have a new GSP for 3 days now. He's in a 2 month old cycled tank.
75 gallon, 2x2x4 ft
Salinity 1.008
PH 7.8
Nitrite 0
Nitrate 20
Ammonia 0
Yesterday he was fine, eating, exploring, today he doesn't eat, swims on occasion but immediately goes back up to surface and looks like he's taking a deep breath then holding his breath, then his body goes limp and he just floats there. He looks a little puffy but not like a full puff at all. He's been alternating between swimming and doing this puff float thing at the surface for 12 hours now. Is this normal?
Thanks.

Since this board has been up, we have found there are several questions that routinely get asked in order to help diagnose problems. If you can have that information to begin with in your post, we'll be able to help right away (if we can!) without having to wait for you to post the info we need.
1) Your water parameters - pH, Ammonia, Nitrite, Nitrates and salinity (if appropriate). This is by far the most important information you can provide! Do not answer this with "Fine" "Perfect" "ok", that tells us nothing. We need hard numbers.
2) Tank size and a list of ALL inhabitants. Include algae eaters, plecos, everything. We need to know what you have and how big the tank is.
3) Feeding, water change schedule and a list of all products you are using or have added to the tank (examples: Cycle, Amquel, salt, etc)
4) What changes you've made in the tank in the last week or so. Sometimes its the little things that make all the difference.
5) How long the aquarium has been set up, and how did you cycle it? If you don't know what cycling is read this: Fishless Cycling Article and familiarize yourself with all the information. Yes. All of it.
We want to help, and providing this information will go a LONG way to getting a diagnosis and hopeful cure that much faster.
While you wait for assistance:
One of the easiest and best ways to help your fish feel better is clean water! If you are already on a regular water change schedule (50% weekly is recommended) a good step to making your fish more comfortable while waiting for diagnosis/suggestions is to do a large water change immediately. Feel free to repeat daily or as often as you can, clean water is always a good thing! Use of Amquel or Prime as a dechlor may help with any ammonia or nitrite issues, and is highly recommended.
Note - if you do not normally do large water changes, doing a sudden, large water change could shock your fish by suddenly changing their established water chemistry. Clean water is still your first goal, so in this case, do several smaller (10%) water changes over the next day or two before starting any large ones.

Is he floating on his back?
You are getting sleepy... you only hear the sound of my voice... you must do water changes... water changes... water changes... water changes...

Re: New GSP floating at top of tank
He was floating right side up (normal)
He passed away the next day. I apologize for the late response.
Obviously something was wrong, but I still thought it was such weird behavior. He really looked like he was holding his breath.
Thank you.
