Might I suggest that this is not a mbu puffer?
A 6in 2year old mbu seems like a statistical improbability, surely if he was that severly stunted he would have died long ago.
However, being 6 inches makes him the perfect size to be in the target family...
If he is a mbu...the tank is 6x3x3...isn't that about 300 or 400 gallons? Still to small for a MBU, but big enough to prevent stunting at 6inches..even with plecos.
Could we see a pic of the puffer or a description?

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.

Stunting, even severe stunting is not necessarily fatal. Ihave know 3" ~30 year old Clown loaches.

I am sure it is possible RTR, I am just putting out some wishful thinking.

Re: mubo puffer sitting on bottem of tank
IME & IMHO, the majority of hobby fish are stunted to some degree. I could point out my first GSP tank as a case in point, a horror show - overstocked, wrong water, but good diet and upkeep. They looked great and held their color and configuration well, they just never grew.. I traded them off after 8 -10 years. They were not more than 1/2" larger than when purchased, if that. Very sad, but I did not know any better.

Too bad the OP didn't come back for an update. I hate that...

Re: mubo puffer sitting on bottem of tank
Yup - we were too insistent on getting answers to our questions. I'll change my diagnosis to way undersized tank, poor diet, and likely bad water - but I would have been gentler about it if he were still here.

Yeah, We've gotta stop jumping on newcomers with improper housing. Lets try to correct the problem gently, otherwise they go away & the puffer is the one who suffers...
