thanks you guys.
It was very hard to start off with.
The Pond I used had been made very hard byt the weather, so had to put it in the veranda with the heating on, to soften it a little.
once i got the First couple of cuts done, it was ok from there.
There is no gravel inside the caves they are bare. the only gravel is at the front of the tank and it is only a couple of cm's deep.
The Slate grass bed is raised of the floor of the tank by an inch, for the banjos and kuhlis.
The Gouramis have taken to living at the back of the caves.
Libby My Giant betta Lives on the Right side of the tank behind the caves n that side, Have made betta Size entrance's Tall and narrow for them to go in and out of.
The Rest of the fish have 8 more caves to explore.
I have also taken into consideration the African butterflys. I have made Large Holes big enough for them to swim in at he very top of the structureso that they go out of the light if they want to. I have 2 Now, Common and Gold.
The rams Love the Small caves in the bottom right corner as do the gouramis when they chase each other, zipping in and out of all the caves.
My Coral Platy and Swordtail spend most of their time with the gouramis at the back of the structure.
the females go everywhere.
I have added some live palnts to cover the surface of the water to make a dappled lighting effect.
Will add the Underwater Lighting System back in tommorrow, wanted to see where the fish spend most of their time first b4 re-adding.
I am Very pleased with the efffect. Have saved loads of money and it is a unique design to me.
