in your main display tank would effectively be live as far as bacteria. The fauna will greatly depend on if they where introduced via detrivor kit or LR
. I would not suggest using CC
in your nano though. You will end up with many water quality issues and due to the work space of a 5 gal
a PITA. I would instead suggest using a good oolitic sand and then bundling up some of the CC
in something porous like cheese clothe or the like where the fauna may work their way out but the CC
will stay put and can be removed later.
Could you post a link or scientific name? Have not heard of this one nor could I find a reference on the web. Most likely it will be too large and active for a 5 gal
nano. What will be the primary filtration?
