Got some bad info about Puffer

HI there I think I was a little misinformed about my figure 8 puffer. First off, the label said when I bought him at the store claimed he was a green spotted puffer, and he was a quote "peaceful fish" well both of those things turned out to be untrue, this is clearly a figure 8 puffer, and gsp's are very aggressive. This puffer was sold as a freshwater fish, so that's what I put him in. At the store he was with other tetras so I assumed he would be OK. Turns out that they need brakish water, and are also aggressive? I have had him for a couple weeks now, and the only strange things that has happened to him was that he ate a dead cherry barb, and got ich, which was treated quickly. Other than that, he has been pretty normal, not chasing other fish around, just chilling and swimming around the tank and being fed the occasional malasyan trumpet snail but mostly bloodworms. It looks like he's fine to me, but other sources say he's in danger. What should I do? He is with 2 pearl gouramis and 5 cherry Barb's, and soon will be with some Cory's and a dojo loach. Any help? Thanks

 

I tried to get pictures of his markings, hope this helps

 

I would return him or set up a separate brackish water tank for him asap.

Would my LFS still take him back? I've had him for a couple of weeks, and I got him from pet supermarket. I really don't have the space (or the approval lol) for a separate tank

I would ask them what their policy is. Most LFS's take fish back. Even Petsmart or Petco has some return policy of 14 days I believe.

I sure hope they do....I wouldn't want to torture this little guy..

 

If they don't, you could find another LFS to take him or look up a local fish club or on craigslist.
