Just tonight I was playing with the lighting and I found that by sliding my light back a little further on the middle brace I can create a different effect of shadows and background color. In addition, I have a new morning bulb setting that is more orangish tone than purple, using a combo of midday and an aqua blue. Now all three events look different, instead of just sharing the morning and evening events using the same bulbs. I have no idea why I didnt think of this before.
So my mornings will be a little more orange-ish now... I'll take a pic tomorrow...and my sunsets will remain purple/pink-ish as you have seen in the previous pics.
I also have two orange spot plecos in qt...LDA31...small peaceful wood eaters, and temp range is from 78-91 F.
