    Hi guys, I am thinking of setting up another shrimp tank and I have an awesome rock for it as the main feature. HOWEVER I am unaware of what type of rock it is and if it would be safe in the tank. Here are some pictures of the rock !

    Any help will be great!

    Kind regards

    Its very similar to the red scoria rock from the NT that is practically impossible to get now.

    I have seen similar shaped rocks in Cape York that had come from ancient volcanoes the reason for saying that is the over all smooth shape as if at one stage it had been melted.

    Out of interest did you find it or was it from a LFS?

    was actually off a breeder here locally (fish breeder that is). Its fairly heavy at around 20-25kg i would say and its approx 55 cm long 24 cm wide and 18ish high.

    It almost looks like there is sand in parts of it as well? So is it safe ?

    Thanks Keith

    Hey Keith thought i would take a few more pics for you. Here is the front view (of how I think i will use it if i can), the back view and also a close up on some of the white stuff which i am not sure if its sand etc?

    Also this rock came out of a chilid tank I have been informed from the breeder I bought it off. I don't think he ever used it but when he got it thats what it came out of.

    I have seen rocks like that about 1mt+ below the surface of the soil and it was ancient Volcanic red rock.

    Soak it for a few days then use a small wire brush and see if the white comes out it could be ash.

    The only other way is see if you can locate a Geologist or take it to a Museum if there is one in your town.

    If it has been in a tank it should be OK I would still soak and give it a good scrub first.

    While its soaking do a few water tests to see if its altering the "parameters"
