This topic seems to come up alot on forums, so I'll give my usual reply....................
While I certainly do not want to shoot down anyones preferrence when it comes to decorating their tank, there are several things to keep in mind when doing so..............
1. Fish can become stressed from outlandish colors in their aquarium!! Colors such as hot pink/purple are not good for the fish.
2. The same hot pink/purple/ bright greens and the like detract from the beauty of the fish and will have a tendancy to draws ones attention away from the fish!!
In essences 9and this is only my opinion) I would stay away from unnatural items to decorate an aquarium with.
Using natural items such as rocks/slate/plants are the better way to go. Keep this in mind.................
Although you are the one who has to look at the tank.....it is the FISH who have to live in it!!!!!!!!!!!!!!!!
