I bought some of these to give my fish more variety - they come in small cubes and the directions say push them against the glass just below water level. They stick for a minute at most and then they are floating around.
Do they come in another form other than the cubes - and if not anyone have a better way to get them into the tank? OR do you just let them float around - I would rather the fish not eat off the surface of the water.
