" Take a Kid Fishing "
would like some input on the pros and cons of a sea urchin in a 55 gal. high tank that will be set up as a reef tank . i know they like to dine on corals, which is a definate con. thanks
 
That's the only con I need...lol
The only pro is that the eat algae, and that they look cool...but they are known to wreck tanks, by shifting rocks, eating corals, removing frags, accidently poking livestock (and you). :)
 
I have a Tuxedo Urchin. No poking, no coral eating (though frags will stick to him as he motors around the tank). Eats a ton of algae. Look into something like that.
 
I'm not sure what kind of urchin i have ( a grouper took my bait into the rocks and when i retrieved my hook and line- minus the grouper- the urchin was snagged.) I know its not the right thing to do ,but i put the urchin into my tank.The urchin is a very dark purple,and about 3" from spike to spike
