Ok. I have a peaceful 90g reef and a 35g. In a year I will be moving to a larger house and will be setting up a larger tank. I know that aggression is eased with larger tanks, but predators will always be predators. But I wonder if it would be possible to house smaller community fish with morrays and a cat shark and harlequin tusk in like a 300-400 gallon reef? I'm sure lions are a no no bit in a large tank I feel like these slower predators may not be able to get these fish in the rockwork.
