100% reef safe fishes and inverts...

ya, ill keep on shifting the urchin from dt to sump, but the light in the sump is on at night, i hope that doesnt stress the urchin... im afraid of hermits since they eat snails

 

Right at the beginning of the video, I swear I see another fish, looks like a YT damsel?

Everyone keeps saying no on the urchin, not 1 or 2. It wouldn't Survive long term, and it isn't fair to the animal to purchase it just to get rid of some algae. As norfolkgarden suggested it'd be a lot easier if you just got some hermits and snails.

 

The hermits shouldnt bother the snails if you have a small handful of empty shells for the hermits to grow into.
We keep about 30+ empty shells scattered across the tank for this purpose. Make sure they are slightly different sizes and all of the empty shells should be a bit larger than what you have the hermits in now.

We have a very diverse snail and hermit polulation. I haven't noticed any problems with the hermits attacking the snails in the past year.
I assume it is because we have a lot of new homes ready and waiting for the hermits.

Rereading the thread, you mention you already have snails?
What kind of snails? Nassarius?

Thanks, Matt

 

I have both a tuxedo urchin and a long spine urchin and they both have ample food and have been in my tank for coming up 5 months. If your worried manually feed them a little bit of food every now and again.

 

i collected from shore, they only eat daitoms and green algae.. some are white/black zebra type and some are tiger turbos

 

none of the hermits available here are reef safe... (Dardanus sp. only)
