Wierd things happening in my tank....
 

I've had my tank for 2-3 years now, but I still feel like an amateur....it's pretty much a 'fish only' tank, with the exception of some fairly recent (few months or so) star polyps.

I have a Regal Tang, and he behaves differently than I would expect him too.....to be more specific, I've caught him hauling snail shells around, nipping at starfish, and even at my spiny urchin! I had one previous to this one that behaved similiarily, so I took him back to the store. That one even went as far as nipping at my brittle star and cowrie. :sad:

Also, my spiny urchin has white bands around it's spikes.....a friend of mine told me it was a zebra urchin, but I don't think so. When it was new and little, it was all black. Is this normal?

Moved to the main reefing forum ... I suspect this isn't buy/sell related :razz:

Edit: Whoops, I see it's a duplicate. Gonna close this one down then ...
