Patience is a virtue. You may have to wait until someone with this knowledge reads your post. Alternatively, you can skim the DIY section instead of waiting for an answer.
when skimming the DIY section i saw a couple of posts where people said it could be done, if not how does everyone else get pieces to stand up without being knocked by big fish
Put a little silicone on your finger and rub it into the grain of the wood where you want it to stick. Then apply more and try it again. I don't know if it will work, but thats what I'd try.
If you're talking about the plywood tanks, the silicon is applied to the front window so it will not fall in. When the tank is full, the pressure of the water presses the glass pane outwards.
