how about this Centropyge bicolor or Apolemichthys xanthotis [quote]
I love your tank. It is a lot of fun watching the growth on live rock that takes place in new set ups. I personally think you tank will never display an ammonia or nitrite reading, so long as you add livestock slowly, allowing time for the existing bacteria in the live rock to spread into the other rock and sand bed.
For the record, adding 5 gallons of "used" water from another tank was a horrible idea. For anyone reading, NEVER do this. There are no benefits of this at all, and the risks of transferring harmful pathogens and parasites are great. There is nothing to gain and a lot to risk. The beneficial bacteria live on the live rock, not in the water.
As for the C. bicolor and A. xanthotis, absolutely not. One of my strongest points of experience in marine fishkeeping is with Centropyge angelfish. I was intentionally specific in mentioning the C. loricula and C. argi as the only 2 angelfish that would work in your tank. For the record, C. ananthops would work as well, but is rarely seen available. There is not a single other angelfish species that would work in your tank size. Not even close.
It sounds like things are progressing nicely. I would suggest adding a few clean up crew members, then beginning to feed a light feeding daily of flakes. Allow a week or so of testing for ammonia and nitrite. Assuming you get test results of zero, then you are ready for your first fish.
For Quarintine, I would suggest a 10 gallon tank. A simple sponge filter, attached to a power head or using an air pump would be adequate. Hydro Sponge Filters | Sponge Aquarium Filters | Filters | Aquarium - ThatPetPlace.com
or Filter Max III Sponge Pre-Filters | Sponge Aquarium Filters | Filters | Aquarium - ThatPetPlace.com
. A small hang on would work also: AquaClear 30 Aquarium Power Filter - 20 to 30 Gallon | Power Aquarium Filters | Filters | Aquarium - ThatPetPlace.com
Regardless of your choice in filtration, place the sponge in the display for a week or so to allow it to seed with bacteria. Then add it to the Q tank. You will keep fish in the Q for a minimum of 3 weeks, and even longer if you see any signs of infection or parasites to treat for.
This topic of Q tanks is coming up frequently and is a long discussion. I will try to find time today to post an article on Q tank setups and care.
