| In Langstone Harbor, Hampshire, England, Schmidt and Warner (1986) found that B. schlosseri paired with Trididemnum tenerurum or Botrylloides leachii, on Plexiglass panels resulted in stand-offs, colonies touching without overgrowth. However, B. schlosseri and the other species were always overgrown when paired with Diplosoma listerianum. | ||
