Should be OK. Most set-ups I've seen w/Lepidio's have either cyps. or featherfins as the mid to upper level action. Also, the Lepidios will hug the rocks more leaving open water for others to play. When the FF start to spawn, the females will need to hide in the rocks to get away from the male which may cause a few fins to be ruffled by the bulkier Lepidio's.
