i was looking to purchase a scooter blenny the other day and my lfs said that my tank needs to be set up for at least six months in order for the copods to form...do they just come out of no where? or should i add a copod cluster? i read that web site u put the link up of and it says each cluster comes with around 100copods...i have a 30g tank...that would be too many right for my tank?
