Ron,
Glad to see the fish return. With the bears, eagle and flowers we are coming alive with nature!
I like the illumination, but could you work a tad on the underneath too. How do you banish reflections from the glass?

Nostrils. They lead to the plecostomus' olfactory organs, which are very sensitive. The sensors are actually on a part of the brain, so there is no transmission system required.(Catfish have a similar arrangement, but their nostrils aren't so interesting.)What are the nostril like organs?
