Is Spotted Puffer Eating My Fish?!

[Steffyboy]

Got a bit of a problem lately.
Bought a spotted puffer last week and totally forgot that they're not the best community fish!
I've noticed today that my 2 large weather loach have chunks missing out of their tails and their fins have been eaten too!
Bit of a coincidence?
Not 100% as i haven't seen him nibbling anyone yet but maybe through the night it has been done.
Time to get rid?
What ya think?!!

Did you not do ANY research before getting a puffer?

 
They should be kept in a species only tank.
They eat other fish.

I've had them before and they were fine (must have been lucky) and it was an impulse buy and it totally slipped my mind.
The fish i have in my tank are way too big for him to eat but i'm nearly certain he's the culprit for the nipping.

Puffers have hard sharp beaks (bird-like) hidden inside the outer mouth, unlike most hobby fish they can bite chunks out of something too big to swallow whole or crush a snail/mollusc shell.
 
You need to separate the puffer from everything else ASAP, with daily 10-20% water changes and initially some anti-bacterial med like Esha 2000 or Myxazin, the wounds should heal over a few weeks. I've had to quarantine a few fish recently after bad fin nipping damage, including a Weather Loach, all are now ready to return to bigger tanks.

Aren't Spotted Puffers also one of the brackish species? My Green Spotted Puffer certainly is.
