I am trying to start a 40 gallon aggressive tank. I am thinking only one fish for this tank. What Kind of aggressives will be able to live in a 40 gallon??? I was thinking a Lion (maybe fu man chu??) or snowflake moray. but I want a cool fish so I am open to any suggestions. any shark stay small enough for a 40 gallon? or octopus?? or puffer??
