IMO: I would have had a light regiment in place from day one.
What did you put in the tank that would have created a cycle? For example, when I cycled my 5g nano, I added some dead rock and a sprinkle of fish food to give it a jump.
How long has it been since you turned the power on (set up the tank)?
I just found your initial thread and read through it. It seems that you are doing all the right things. I would definately add your CUC now. Be certain to drip aclimate them... invertibrates are very sensitive to changes in their environment.
I was worried about adding too much cuc at first. It seems as though they wouldn't have much to eat at the moment. I was thinking about adding a fish and a small amount of cuc every week or two till I reach the desired amount. Any advice?
