Thanks for the links, Don! (Love the glass bowl feeding trick and will try it tomorrow!) I'm on the right track with the tank as I have live pothos planted in Coc. husk and that is the substrate also. Glad the 3 ft. height will be good, but is it okay to put them in that large of an enclosure (108 gal.) soon or should I wait awhile? Is the 10 gal. big enough until then or do I need an intermediate size in between tanks? How do I know when to switch them?
