Mini cycle?

[Lofus]

The QT is 30 gal was and has an Aquaclear 150 and two sponge filters one sized for a 10 gal, the other for a 20 gal. It was set up and cycled using two cocktail shrimp. Three months before the fish showed up. Performed a 50% water change prior to introduction of the fish.

I broke out my ruler and no compensating for paralax on the glass, the Tang is 3" not 4".

None of the fish are showing signs of stress.
