Hi Guys:

Need some help. I am trying to make a 50-50 set up for my African Bullfrog. half aquatic half terrestrial. I have a 20 gallon long tank, and already have had a piece of 3/8 glass cut to act as a divider between the water and land portions. My question is how to secure the divider and seal it. I have bought aquarium silicone which should accomplish the sealing portion yet I am nervous on how to secure it in position. Any ideas to keep it upright ?

Thanks in advance.
