Entropy

I just turned mine in at RCA. They gave me $10 in store credit. It was a beautiful fish, but too aggressive towards the rest of the fish at feeding time. Also it is basically the last fish you are putting in, because mine beat the heck out of anything I tried to put in after.  My diamond goby was the first victim, then a chromis. Fortunately I pull it out before it killed any fish, but I had to pull out all of my rock work to catch it. Mine was also a snail/hermit connoisseur.

I don't have the setup to raise them. I am guessing with my two wrasses and the clowns themselves there will be no survivors. I wonder what you get when you mix a false and true percula?

My overflow is almost completely silent. I am running a gate valve on the drain, and have a second drain that is a bit higher and only gets used if something goes wrong.  I have to adjust it about once a month (usually when I mess with something), but it is pretty much hassle free.  You can do it with any tank that has two bulkheads, but it is easier if you have three (two drains + one return).

Imo these are all simple adds:

Melanurus Wrasse  (you need a lot of sand for this guy)

Orange Stripe Prawn Goby (you need a lot of sand for this guy)

Diamond Watchman Goby  (you need a lot of sand for this guy)

Blue Eye Golden Midas Blenny

Australian Black Percula's x 2

Purple Firefish x 3

These are hard especially with the competition above for similar food sources.

African Leopard Wrasse – one male, one female

These are iffy (temperment): I would add these at the same time down the road after the list above gets good and settled.

Heniochus Black & White Butterflyfish

Kole Yellow Eye Tang (add last with other tangs)

White Cheek Tang (add last with other tangs)

Blue Caribbean Tang (add last with other tangs)

I know that kills your free shipping plan, but 15 fish is a lot to add at once.

Are you sure the bottom of the tank is level? I always use 1/2 inch foam under my tank for this reason.  Foam is the great equalizer.
