Good point! Things do transition “positively” at times. Nature does that.The most interesting part to me is watching the way these tanks take shape. I don’t try to get grid of the nasty phase as soon as they begin and instead I enjoy watching it and how it ages.
I love watching the corals grow in too. Just watching how each polyp multiplies and replicates itself as the skeleton grows. Plus you have the colour as the coral drag ages. The colours change and some become much more dominant than others.
The final thing is, watching how each fish reacts with the surroundings in a much more natural way. And how they change as they age, for examples Bangaii cardinals as juveniles will group and hide within the spines of a Long Spine Urchin, but when they age they start to split off and find their own hosting LS Urchin.
