Our host sells the same type critters for a much better rate....please refrain from advertising products and prices from other vendors!
All the critters you mentioned would do well in a established reef...all would help to keep things under control...but I would advise against the red legs...they tend to be overly aggressive in my opinion.
Despite what some folks think...un-controlled pest algaes "need" to be controlled or they can over come the balance of a reef system which may result in a cess pool like display that appears green watery and stanky!!!! Personally I would use all tools available to control/remove pest algaes before they become the dominante feature of your reef!!
