Aquarium background...?

who knows a way i can make a really nice and cool looking surroundings for my 2.5 gal tank... i tried cuting out pics but it didnt look that good
Paint it.Get some acrylic spray paint,tape off what you do not want painted and go to town.Painting is by far the best environment you can get.
Get poster article (whatever color you desire) and make whatever design you like. Then laminate it to hold on to it water proof, then attach it to the back of your cistern.
Answers:    You can buy backgrounds. They don't cost too much.
go with the answer above or only buy a small one a cut it
How copious small fish can you hold within a 2 gallon cistern?   Driftwood next to slime on it?   Seriously injured fish?   Anyone preserve Monster fish here?
