the lfs says that the blueline is not going to sell for a long time and im in the process of moveing but my miniatus hardly eats and doesnt grow the lfs says they are powerfeeding the grouper prob for me since i was the only person interested in a blueline the blueline is about 4-5 inches and my miniatus is about six so if the blueline is 5ina 1/2 inches and my miniatus 6 and 1/2 inches in a mounth would it be safer?
