thank you! i used some craft mesh i got from our "hobby lobby" then cut it to size, and placed the black report cover things, uh i forgot what they are called, like what you would slide down a bunch of papers in a report to keep them together. put one on each side of the mesh against the sides of the tank to keep it upright.

i love ur tanks! i hope i can have something like that. what did you use as a divider? did you attach it to the glass? thank you!
