Threadfin Cardinalfish (How Many Should I Get?)

[CoralNerd]

Blue Streak Cardinal (Zoramia leptacantha) http://www.orafarm.com/images/products/fish/cardinals/bluestreak_lg.jpg
I currently have the following fish:
1) Purple Firefish
2) Yasha Goby
3) Yellow Corris Wrasse
4) Yellow Corris Wrasse
5) Ignitus Anthias
6) Zebra Barred Dartfish
7) Tailspot Blenny
8) Tanaka's Pygmy Wrasse
9) To add McCosker's Flasher Wrasse
So 9 fish total.
Right now my system is so clean I need to add some more fish so I will have more nutrients. I feed a decent amount live and different flake food. I turned my GFO reactor off recently and I still only have .19 phosphates. Skimmer has been turned to dry skimming. I have a nice skimmer and nice sump with refugium. It's about 85g to 90g 46" x 20"

So how many threadfin cardinalfish should I get? I'm thinking 4

I personally would go with 5-7 but then again I always err on the side of over-stocking.

those threadfins have been so challenging for me to keep :(. I'd say get 10 if you want 3 to live...

I got 5 all doing good, knock on wood. I'm on the 2nd full day. Super cool fish!
No shipping, the retailer picks it up from the wholesaler and the same day I get it from the retailer. Proper aclimate match salinity, and aclimate under 45 min...in the tank. Crossing fingers all is good.

It's been one week 3 are eating, and 2 are not eating. I put a little garlic stuff on the brine shrimp, and mysis but no luck so far from the two that aren't eating.

I have to say I love these fish their awesome.
