Biocube29 from mantis tank to Clown heaven

[Polscot]

they acctually are reef safe, there not as bad as everyone says they are, the most ud lose is the odd clean up crew (there cheap so who cares), specially if u keep him feed every second day, which is fun to do, aahope has a reef bio cube with one in it and its fine, and the local FS has a massive 100g reef with a smithii in it and ud never be able to tell, there really not that destructive (AS LOGN AS U GET A SMASHER) as spearers kill fish
