Not a good idea .Anglers are ambush predators. If any other fish is smaller or even close to the same size and your angler is hungry it will be lunch no ifs ands or buts about it. This angler is almost a foot long correct? One that size will take down larger fish with no issues. Sorry for being so blunt and I hope I do not come off as rude but it's really not an ideal situation your planning these fish are not peaceful or passive when it's lunch time .
