I use terra cotta clay pots for hidey holes. :) I also got some rocks from my back yard (washed them for about 10 minutes straight of course!) and made bridges and caves. Works great, and the fish love 'em!
I just picked up some shrimp! Pet supermarket would only let me get 10 for 1.19... i couldnt get any less... Ima put 5 in the 10g sorority.. then i gotta put 2 or 3 in each of my 2.5 gals i guess lol.... well see how this works out.
