Tropical - Fish - Pictures .com

This is a tropical fish site for all tropical fish enthusiasts from beginner to expert. It has some nice tropical fish pictures and will hopefully have something of interest for all freshwater and marine fish keepers. These tropical fish pages provide some information about some of my favourite fish, along with tropical fish pictures of them. I have kept fish for many years now, ranging from community to marine. Over this period I have been drawn towards catfish, and the cichlids, which I must confess, through there antics have become my favourites. I now keep African and American cichlids, along with some catfish and plecs.

Gravel

Gravel plays a number of roles in the aquarium:

  • it anchors rooted plants, stopping them from floating up to the top of the tank;

  • harbours good bacteria that eat left over food and fish waste, keeping down harmful tank chemicals and pollutants;

  • provides colour and decoration, making the appearance of the tank more pleasing ;

  • catches fine debris that would be stirred up by the fish and water movement making the tank appear cloudy.

The choice of gravel should be made with the following considerations: pleasing to look at; no sharp edges; chemically inert; thoroughly cleaned before use; about 2 inches at the back banked down to 1 inch at the front is ample and looks good.
