Lava Rock

[fish_face]

Hello,

I'm trying to buld a largish cave for my 350 litre (75 imp. gal) tank so that I can get some dwarf cichlids to go with my angelfish and catfish. Does anyone know what the best thing is to use when sticking the rocks together?

Hi, just a little update - I used sillicone for the base and milliput to build the rest up in the aquarium. Thanks for the help.
