Hi Guys, I need some advice. I need to keep the top of the tank open so that my RTG arowana can enjoy little bit of jumping. Since two sides of the triangular tank is covered by walls, I need to worry about the front side only. What I need to do is put a vertical net or a glass along the top line of the front panel. The choices I have is a net or a glass (do I have other choices?). A glass will be more clear I think but a net would be cheaper and safer (won't break). But don't know whether the net will look messy since it will be right in front.
Please help me with the ideas.
A friend of mine did the glass sealing to concrete part for me. It is a black silicone but I'm not sure what brand it is.
