I can only say I had to remove rock and wood to get 3 bristle nose pleco's. The darn things were fast!
My boyfriend used 2 nets and herded them in,lol, it was a riot
But seriously if they're that fast you're going to have a bit of a mess. When I took out my Geo.Steindachneri from my 75g I had a bunch of uprooted plants.
