Can I add any puffer as a tankmate?

150 is not too small for a ck. They rarely reach or exceed 24 inches in captivity.

That said, I may be able to get a larger tank. Lets say I get a tank large enough for a large freshwater puffer. You're saying the mbu puffer would most likely kill my clown knife, severum and bala sharks?

yeah proboably, and a mbu will need at the very minimum 300+g and massive frequent water changes.

house the ck how ever you see fit. they rarely reach 24" due to improper care.

Don't plan on putting a puffer in with your fishes, coz there is a possibility that the puffer might get a chunk out of your other fishes and die or your fishes might want to get a nibble of your puffer and die in the process coz puffers have toxins.

Recommended tank size for a mbu is 1000g, due to hit's HUGE bioload.

Only FW puffer that would not pick at your other fish would be a South American puffer (likes to live in shoals--needs regular teeth-trimming). They would get eaten by some of your other fish though, as your fish grow larger.
