What type of gravel do you think look best in a red bellied piranha tank

  • We are currently upgrading MFK. thanks! -neo
Since I went with a dark tank (big rocks, driftwood, anchored and floating plants, black background) I went with white gravel. It actually looks pretty good IMO :)
 
black sand. Brings out the colour and piranha are messy eaters, you don't wan to vac your gravel.
 
i went with pool filter sand, it looks good right after i clean it, but gets dirty and looks bad fast. i'd probably go with spirit's suggestion
 
Finely crushed gravel. Its the size in between regular gravel and sand.
Gives the amazon feel and at the same time prevents a certain degree of waste from sinking into the substrate.
 
black gravel , i like the way sand looks but i dislike the toxic gas pockets that can start to form if your not stirring it up enough, wich can be fatal to your fish.
