Ok, but I will just tell you this my pleco around 32cm some how manged to tip my massive boat in the tank over. the ones you get from animates that come in 2 halves.
hey ryan with plecos and other big catfish you know how the really like to get on your nerves and push ornaments over and rocks etc would they be able to pus limestone ones over?
ok i just thought that maybe from the rock pools would be good as that is what the marine labatoury uses to feed there sea horses etc (mind the speling)
