Longnose hawkfish
Don't add a jawfish, especially not a blue spot. Jawfish need at minimum a 5" sandbed to burrow, and blue spots are temperate species that will only live comfortably at the 66-70 degree mark.
5 fish is all I would put in a 37 gallon, especially one being a dwarf angel because they have a higher bioload. The cherub angel can also be pretty aggressive.
+1 my only (at this time) and favorite fish!
Is that too much bioload for the tank with the five fish I already have? I have the Reef Octopus 1000 and am adding a canister filter.
