Kinda looks like a much larger version of the two babies i picked up this past weekend and am endevouring to get settled in. They kinda look like Takifugu oblongus....so many of those fish have rather cruddy pics online so i'm having a helluva time sorting them out.
Hi, I am the one that owns this puffer. I have had him for almost a year. I am concerned that he may need salt water. He seems failry happy still and eats well. Every so often though he will flip out and flutter violently at the top of the water but then calms down. He doesnt puff up or anything though and my someone is at the house constantly and would have noticed if he did. I need to figure out what kind he is? Do you think the faded black spots are from lack of salt? Thank you for your help
If you have a space in your URL, simply replace it with %20 and your links will work properly. Just be sure to turn off spellcheck, because spelling cow will automatically change the %20 into a space and screw it up all over again.
tankbuster, you should check out the pufferlist. Maybe by reading the information on the various puffers that looks sort of similar you can pick a few that sound accurate based on his size, etc.

We had a couple of Green Scats in FW when we first started keeping fish, and they did fine for the first 6-8 months, then they started flipping out like you described, and within a couple weeks both had died. I found out later that the most likely cause was that they had matured to the point that they needed salt (and minerals) in the water to help process oxygen, and without it they suffocated.
It is not really suffocation. Fish have very polished processes for maintaining their blood and tissue chemistry. If maturation involves a move to harder, or softer, or brackish, or marine conditions which are different in osmolarity from those in which the fish is bred in the wild, the enzyme or active transport or excretion or metabolisn of ingested or passively uptaken minerals or H20 itself will develop and come on-line as the fish matures. If the fish is captive and held in water conditions inappropriate to its growth stage, it may not be able to osmoregulate and hold its blood and body chemistry where it should be. The fish which cannot osmoregulate goes into acidosis or alkalosis, suffers, and may well die. Best case it will be more fragile, prone to disease or infestation as well as stunting. Worst case it goes into shock (aka osmotic shock, erroneously known as pH shock) and dies horribly.

I'm still leaning towards this species...but then again i've been staring at Takifugu pics nightly since friday and they all start to look the same to me.
