So my minnow guy is going to get me a gallon or 2 of fhm to put in now. He also said he has some emerald shiners to get rid of if I wanted any. I was doing some reading on here that if they are true emerald shiners(seem fairly easy to identify from one of bills posts) then chances are that they will not reproduce and will not get bigger than 4-5inches. Would you be concerned about putting them in with no predator fish? I know if they are GSH they would prob grow to big to be eaten once I get my predators in.
