What kind of rock?

Postby Fishbguy » Thu May 08, 2008 11:10 am

What kind of rock do all you use in your tanks? I'm trying to decide between lace rock and river rock.

What does everyone else use?

hmmm...so many choices :lol:

What about rocks you use in tang tanks? Does anyone know what kind of rock, or some kind of counterpart, is found naturally in lake tang?

I'm using black lace rock over #1 crushed coral with 50/50 10k/actinic lighting, effect is this:

I would imagine - based around what I've read about Lake Tang - that most of the rock found in it is volcanic, though it's probably been smoothed quite a bit over the years by water currents.

I use River rocks in some tanks, Lava/Volcanic rock in others and made the mistake of buying feather rock. I tossed out the feather rocks, and added smoother river rocks.

No, its not volcanic!

I use river rocks. Volcanic rock can be dangerous because its sharp.

Wasn't the lake created by a volcano somthing like 20 million years ago?

I was just watching Jewels Of The Rift and everything around the rock dwellers looks like black river rock with pourous surface.

hmm..those pics are pretty...the ones from the lake. I can't seee the other one because I"m at school.

It looks like irregular shaped river rock...maybe I can recreate it using smoothish pieces of lace rock. ...

A quote from Wikipedia about the Rift Lakes
The East African Rift came into being approximately 40 million years ago as the African tectonic plate began to split. Lakes such as Lake Malawi and Lake Tanganyika have formed in the various valleys of the rift zone, including the huge Lake Victoria.


They are basicly collection basins where the sliding techtonic plates left depressions.

I prefer rocks that sink ;). It all boils down to what you think looks good. I'm probably going to try to find something like lace rock, just because my tank is smallish (29 gallons) and I think it takes more space to get the right "look" with a smoother rock.

I think that I'll go with lace rock because the tank is smaller (29 gallons) and I am having trouble in my 40 tall (same foot print as a 29) using slate.

I just go down to a lake near me and get all my rocks for free... clean and sterilize and you are good to go. With all of your back door open to you, depending on where you live you have a pretty good selection open to you and to me ends up making a more natural looking tank, than one with all rocks the same exact color and makeup. Just me though, some of my first mentors were very much for very natural tanks and setup several tanks by going to the stream behind their house and and collecting everything for the tank - gravel, rocks, driftwood and stream 'litter' and water. Made for an amazing looking tank. A lot would cry foul as it could introduce parasites and such... but the fish that are F0 come from nature with all these parasites and all. It is a risk to introduce a pest though so that route is more for seasoned hobbiests as why if you collect rock from lakes/streams I do say to sterilize them to be safe.
