help. how to make tank dig proof

hey guys well i want to get a blue spot jawfish only one problem they dig and my rock are on top of my sand. my tanks been running for awhile now im arfaid disturbing the sand with screw things up? i know putting pvc under the rock structure can support it but how do i get it there?? any advise would be a help thanks

 

How deep is your sand bed and how much rock are we talking about here. If your bed isn't too deep, then you can just push on the rock and wiggle it through the sand down to the bottom, doesn't stir up the sand or anything. It's what I had to do to mine when I got my goby.

 

Take the rock out and buy some egg crate. Place the egg crate in the sand so that is is on the bottom glass and slightly sticking out of the sand where your rocks will be. Put the rocks on top of the egg crate and your good to go.

 

the sand bed is about 3 inches and theres about 60-70 lbs of rock its inna 55gal....

as far as egg crate i thought of that but then the jawfish wont b able to dig uder the rock

 

any more suggestions?

 

bump anyone ?

 

I would pull the top rocks out and put in a bucket of water. Then take the bottom rocks and push and wiggle them down until they are sitting on the glass. Then put the rocks that were on top back in. JMO

 

Exactly what I would do.

A more important question is how old is the sand. If it's less than a year it should be fine to move around a bit. Mine is going on two years and I move it with no problem.

 

wiggle it down brother

 

its about 7 months old i suppose.... i would but all the cool caves happen to be on the bottom of my rocks haha so im trying to think of a structure to support them

im thinking of tarcing a rough pattern of the rockwork in egg crate and cutting it to fit leaving openings to dig

or

laying 3? inch pvc down on its side ..sliding it under the sand and rocks ?

what do you guys think about those ideas?
