Placing Rocks In Aquarium

[Matt Gleadow]

I'm going to be building a rock stack in my aquarium. Is it ok to place the rocks straight onto the glass? If not what can I put underneath them thats easily available? Also will the sides of glass be strong enough to support the rock if I decide to stack them in a corner against the glass? Or am I best off having them free standing?

Dont want to put them on the sand as if I get fish that like to dig in the sand they may cause a rock collapse.

good question!!!!!!!

i would be inclined to stick the rocks together with silicone, this avoids the chance of collapse, and will also make the whole lot free standing.

You should place a piece of styrofoam under the rocks to distribute the weight.

First, if you do not have a floating base aquarium (i.e. AllGlass brand in the U.S. has a floating base), you will need to support the bottom of the aquarium by resting it on top of a cut-to-fit piece of styrofoam.

Next, go to an electrical supply/hardware store and purchase "egg crate" louvres for lighting in a drop ceiling. Cut it to fit the inside bottom of your tank. This will keep pointy edges away from the glass (also makes a great root anchor for live plants!!)
Place that in before anything else, then stack your rocks on top. Use aquarium safe silicone to keep the rocks in place (no squishy fishy!).

cheers!

EDIT: after the rocks are in, add your sand, this will keep mbuna or other sand diggers from causing an avalanche.

You can use a piece of slate as a base then attach your rocks to it with aquarium silicone.
