You can also place the bottle in upright.

And what exactly is the point of that?

Burrows

Maybe I'm just too darn dyslexic to understand. There's a bar of water inside the bottle?

Either way, fiddlers will not dig burrows in gravel, nor underwater.

Just forget it, I'll invest in sand

You will thank yourself later.

You can also use mostly gravel for the land part, as sand will move over time. Be careful of anaerobic pockets in it though.

If you get playsand, it's cheaper than gravel anyways.

 

[goldfish12]

where can i get playsand? How much does it cost?

 

[tranceFusion]

it costs like 4 bucks for a 50 lb bag. you can get it at home depot or lowes.. you will have to wash it very well.

a fiddler burrows in the substrate just enough to fit inside, and the substrate closes in around him.. you cant just put a 3" diameter hole in the gravel with water in it.. that makes no sense..
