Thanks so much Gruff master. I think I got somewhat lucky in composing the contents of my tank. I feel blessed to have come up with something that is somewhat natural and colorful.
When I get the next tank, I am pondering a change to sand, from gravel.
Thoughts? Also, when i change to the next big tank, my 4 big guys need their own hiding spots. Any ideas on a natural looking set of hiding spots for each of them? I have found that creating a "bullpen" type of cornering seems to be enough, it doesn't have to be a cave style enclosure to make them happy. Those would remain for the loaches.
Cheers,
Joshua
