My 55g tank is finally stable after 5 weeks or so with nothing but a cinnamin clown in there. I know, generally a bad move but I had him in a 10g that I wasn't maintaining as much as I should have because I was so focused on my 55. He's doing great though, very active and greets me at the front of the glass. So two days ago I decided to get a few inverts. I picked up two coral banded shrimp, 3 Nassarius snails, 2 scarlett reef hermit crabs and a feather duster, just because they seem really easy to maintain at work. One of the snails died, but everything else seems okay. I have enough algae and detritus by now that these guys should be happy I think. Anyway, this morning I saw my duster hanging about halfway out of his tube and got a little concerned, so I moved him closer to a powerhead. I got home from work today and found him lying on the sand, crown still intact, squirming around a little bit. I'm wondering now if they need lighting similiar to corals. I did google the subject but everybody seems to have different opinions. Some are saying it should be gently shoved back in the tube, others are saying to leave it alone. I also found out that they can just find the spot they want and create their own tube, but most people's dusters seem to die before that gets to happen So what should I do? Parameters are: PH: 8.2 Ammonia: .1-ish ppm Nitrite: 0 Nitrate: 5 KH: 250-ish hard to tell with these test strips Salinity: 1.024 don't have a calc tester yet I've got around 40 pounds of LR right now, will be getting more. I only have like 450 gph of flow currently, but I'm looking around at wavemakers and plan to order one as soon as tonight. MEH NEEDS HELPZ
