Anyone know much about these?Mine keeps moving all around (thinking My fish think its a basket ball lol)
Is there anyway to glue this puppy down?

Thanks!

Mine hasn't attached so this is what I've done. Make a hole in a rock put it in spike it down with tooth picks I broke them in half. Best way I've found so far. Good luck their slimy feeling.:biggrin:
