Puffer Compatibility

[tntahan]

I have a semi-aggressive freshwater 46 gallon tank. I have about 10 fish in there ranging from a rainbow shark to a few tiger barbs. All the fish are young and all around 2”. I also have three Red Clawed Crabs. My question is can I get a Figure 8 Puffer in here without everything killing each other? I know these puffers eat snails but will they go after my crabs? I read that Figure 8’s can nip at other fish, but then again the barbs do that anyways. Anyways let me know what you guys think or if any of you have done this.

I would say no they can be very nippy and territorial. Also the crabs will kill your fish if they get ahold of them and the rainbow shark as he get older will need a 55 gallon because they get aggressive.
