My old two Beta tank's divider was broken beyond repair. I searched for something the same size as i have my tank on the pass through between my kitchen and family room.
The blue tint to the tank glass is just the right hue for viewing the Betas as I prepare meals or look it from my brunch table in the family room. I did add my tiny seashellls and some glass "gravel", imitation starfish, other glass fish, two tiny blue ocotpus from my forner tank
