Hello! I am fairly new to the saltwater side of the hobby, and I have a 10 gallon coral tank with some montis and softies that I like a lot (no fish rn, might add a tailspot blenny or something similar). Either way, I'm liking the marine side of things a lot, and I was considering getting a 40 gallon long for fish and I was wondering if a Valentini puffer and Longnose Hawk together would be acceptable, both in terms of aggresion and tank size. If not I was also considering one or the other.
