New tank

[verojeremy]

I was thinking of starting a new tank. I want to do fish that I can't have in my 75gallon because they would beat up on my mandarin or eat my clams. I am thinking about a leopard toby puffer, a Caribbean redspotted hawk-fish, and a wartskin angler. I was thinking of a 40 breeder and have it connected to my 75's sump. I have an swc150 skimmer, a fuge with chaeto and live sand, a phosphate reactor and about 80lb of live rock and a 1-2 inch layer of sand. I have 5 fish in the 75: yellow tang, mandarin dragonett, melanurus wrasse, pair of occ. clown. I am thinking the puffer won't get eaten by the angler because it is poisonous or that some puffers are, would the puffer peck at the angler like they do loins, and would the hawkfish be fine?

The toby will likely pick at the angler, and poisonous fish don't get a free pass in the food chain...if the angler can eat it, it will do so. In fact, both fish will likely die if there's an "incident". BTW, leopard tobies can be a bit touchy in terms of hardiness.
Your hawkfish would also likely become "lunch" for the angler as well. Anglers are REALLY best kept in species setups, as they will try, and can eat prey larger than themselves. When this happens, the angler usually dies due to the food item decomposing in their GI tract before it's digested (anglers have VERY slow metabolisms).
