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.

"blind puffer"
I need help. I have a stars and strip puffer fish. Ive had him for about 3-4 months now an he has been acting fine until now. He use to eat regularly no issues there i would walk by his can of food and he would know he was about to get fed. Now he wont eat and when he swims it seems like he cant see. His eyes look fine are not glossy or cloudy and no he does not have ich no white spots on his fins or anything this tank is cycled and never had an issue but it seems like he cant see. He runs into the glass into the sand and rocks i know he can see me though because his eyes do follow me. I just dont undersand why all of a sudden he wont eat and seems like he has a hard time swimming now. He is about 6" long maybe, in a 90 gallon tank all levels and silinity are correct so i dont see why all of a sudden. If anyone can help me PLEASE i dont want to lose my puffer. He is always hungry and hasnt ate in about 3 days. Someone please help!!

Re: "blind puffer"
This sounds like the levels are off, but no way to know; could you please answer all the questions above the post in red?
Also include his diet, specifics on what he eats.

Re: "blind puffer"
Does he only eat freeze dried krill?
It is absurd to talk of one animal being higher than another. We consider those, when the cerebral structure/intellectual faculties most developed, as highest. A bee doubtless would when the instincts were.

Re: "blind puffer"
I have almost an identical set up to you, all the way down to the puffer. Mine was the same as yours, always cruzing the tank and would know when he was getting fed when I would go to the food area. The all of a sudden he was running into things and not eating. Well I did an 85% water change and dosed the tank with epsom salt for constipation. He ate this morning for the first time in 2 days. Check your levels, like seven said, they may be the cause for the weird behavior.

Re: "blind puffer"
I'm with Flutter on the krill, could be lockjaw.
I don't know the treatment for it, but I'll try to find the link.

Re: "blind puffer"
Yes he has always ate the canned dried shimp he LOVES them. About 100lbs of live rock i know what ich is and had to treat another tank for it so i know its not that so i checked the levels today and they seemed to be like always thats why i was wondering why hes acting like this and didnt know if anyone else has seen this.

Re: "blind puffer"
Very helpful thank u i just wish i knew why hes running into the glass now and everything in the tank.
Re: "blind puffer"
It's a classic sign of nitrite poisoning but if your values are fine then I'm really not sure. I'd do a large water change but beyond that I don't know. Best of luck.

Re: "blind puffer"
Because he is likely sick, if he's only been eating krill, that not only isn't nutritionally sound, but it has been linked to lockjaw, as the link explains.
If he's feeling sick, he's likely to not be able to control his movements as well, or he's just too weak, or he's distracted with how he is feeling.

Re: "blind puffer"
Ok i have fed him frozen shrimps the ones u let thaw too but he would just filter most out of his gills so i figured he liked the dried shrimp better.
