Hi All,

First time poster here, starting my first reef tank. My tank has done its initial cycle after a few weeks with the lights off and I just started to stock very lightly. I used 120lbs of dry rock with 5 live pieces to seed it and 90lbs dry argonite sand. I put 3 small Chromis, 2 Firefish and an Arrow Crab a couple days ago. I have started a 9 hour daily light cycle with 3 hours of blue light in the evening. So far everything looks good but I really want to make sure I stock this tank responsibly. I would love to hear a few suggestions on how you would stock this tank if it was your 125 Gallon.

I would like mostly peaceful maybe one or two semi-aggr fish max, that will get along with each other and coral. I plan on having mostly softies and leathers and some inverts. I would like a pair of clowns, the LFS store has a coupled pair with an Anemone they stay with all the time. Are anemones dangerous for my future corals?

At this point I am a bit lost on what I should add next. I feel like cleanup crew has nothing to clean so maybe some more fish first till I get an algae bloom. My plan is to have a couple feature fish and then mostly small schooling type fish. I was very interested in the look and personality of a blonde naso tang but I've read my tank would be too small for an adult one and eventually I would have to give him back. So i guess what Im after is understanding the order in which to do this. Should I add more chromis and Firefish, (maybe a peaceful colorful wrasse?) and smaller stuff first then add a few larger fish (tangs?) then my coral then my cleanup crew?

Go slow and take your time.

What lights are you using?
Are you using RO/DI?
Do you have a sump? An ATO?
Test kits?
 
Sump is ;
44 inches long - 12 inches deep and 18 inches high.

Overflow box with two U hose siphon. Return Pumps 2 Rio 3100
Yes RO
Yes I have Test kits for Ammonia, Nitrate, Nitrite and PH, ordered a TDS meter I believe its called for phosphate metals etc,
I have a Phosban Reactor but not setup yet.
no protein skimmer yet, not much room in the sump I think im getting a HOB
 
what skimmer?? tank looks too clean, you sure the tank is cycle
The tank ran for 3 weeks with 5 pieces of live rock and added bacteria in liquid form. Hard to see in the pic but here is a close up of one of the live rocks. Ammonia spiked and then came back down, Nitrates spiked soon after and everything seems leveled out. My PH though is a little low it hasn't hit 8 yet. Brought water to LFS every week until he said it was cycled. I will get details on the lights, 2 are fluorescent reef lights and 1 unit is blue and white LEDs. I do not have an ATO I manually pump from my RO Can every 2 days.

if you are planning to be a reef tank, then i suggest you get a good skimmer first, not hob type. for a 125 gal tank get one that is rated 200+ gal
 
Well just learned my first lesson of many Im sure. Woke up this morning to see my Arrow crab eating a chromi. 2 are missing, I am assuming he killed them and needs to go back to the LFS.
 
Looks like he has a taste for blood now, hes swiping at my remaining fish!
