I want to put two goldy pleco together, if my tank is big enough with hiding spots, will the two goldy pleco be fine together or will they seek each other out to fight? I am also thinking about a L191 royal and a L47 mango. Will the L47 and L191 be fine on a hikari cichlid gold and new life spectrum? I heard that L191 are messy, will they eat all my driftwood? How is the appetite on the L47, because my goldy L14 always has a nice big full stomach. And my goldy is really active, how does the L47 and L191 compare to my L14 in terms of activity and appetite?
