Fish Stck Behind Backgroud

[tez2k007]

I have a 3d background in my tank. Some of the smaller fish including my cardinals have managed to get through the small gaps at the top of either side and are just staying there. Because its stuck to the tank I cant exactly pull it off. How can I chase them out first of all and what could I use to block the small gaps. Any ideas.

it will be hard to black the gaps
the fish most are most likely staying there hiding and i'm pretty sure they can get out of it, otherwise they would've had a hard time getting in.

Yeah they probably can get out. Just dont really want them getting in. I mean what will happen once I start draining the water. If they are not quick enough then they are in trouble.

for thhe gaps you could use some reef epoxy about 5 pounds ffor a big bit it sets hard and can be used in fresh and saltwater and it can be used under water while the fish are in the tank

If you have a spare one you could use one of the rubber thing that are use to stick filters and heaters to the tank or clean blue tak or something like that.
