Also - if at all possible arrange your rock and powerheads so there are no 'bridges' to the intakes. The rbta will not 'jump' or 'swim' over distances. So keep some safety distances around danger areas. Rbtas like deep recesses in your rock where they can plant their foot and then stretch out toward the light. Be deliberate in creating these sort of spaces far from danger areas. Once they find these happy places they may settle and stay put for long periods.

But in the end -- these critters do go a wandering sometimes. It's like watching your kids playing in the street!
