Most of these rocks are 3kg and above
Galapagos Rock is a wonderful aquascaping rock with huge potential. The porous and slightly rough nature of them means they not only look amazing but are great for attaching plants such as Anubias, Microsorum or Moss. They are very easy to work with too and even beginners can create lovely aquascapes with minimal effort/skill. However, this is only possible if you buy enough - the picture shows 7ks of rocks so bear this in mind. You generally need more than you expect and with too little and you're often disappointed.
Most Galapagos Rocks are dark in colour but there are some which are slightly lighter.
Sold per kg and most pieces are larger than 1kg.
