TOTM isnt just about the pictures, it would list equipment, cleaning, livestock, the loverly cranberrry juice bottle they use for a collection cup, the soup can

(yeah, i got rid of that a few months ago :P)
I check out the picture section here maybe once a month, and even then.. its just to drool at peoples corals/tanks. There is little or no information about how the tank is taken care of, what they are doing etc etc etc.
I don't think it should be voted on per se, but someone will have to make some sort of sellection. Not based on how 00ber it is, rather to change it up and show different types of tanks each time.
I think quarterly would be great for this small a board.
The greatest part of this would be that we could all share and comment on the tanks. Find ways that other people have saved some cash, where they have tried, and failed. What we would do if we had some of the same issues etc.
I can find tanks to drool over any where on the internet. Most of the time/money that they have for them is nothing but a dream for me, and frankly, I have enough unatainable dreams :P
