It's not really what you're asking about here, but I just came across a new book I hadn't ever seen before, and thought I'd mention it. It's called
Dynamic Aquaria, and it's all about setting up tanks that mimic natural habitats, like biotopes, and river tanks, and tidal pools, that sort of thing. Anything where there are dynamic conditions, like mangrove habitats with high tide and low tide, those kind of tanks, are what is talked about in this book.
I almost bought it until I saw that it was $85!! That is not a typo. It appeared to be a text book of some kind, but I can't for the life of me imagine what class it's a textbook
for. I missed out on some good classes in college, apparently.
Just thought I'd mention it here since this is a thread called "good book."
