Running 20G tank - Edmonton
 

Have been running a 20G for quite some time now, which has nothing in it other than a crab or 2.

Noticed a lot of copepods/anthropods roaming around. But not sure if Im willing to put a fish in the tank.

Anyone have any livestock they willing to give (for free) or sell (cheap) so I can test the water??

thanks.

How long has the tank been setup?

Normaly the pod population balances itself out over a month.But If you are determined.....6line wrass?

Should be thinking about getting a test kit to check your tank's parameters.
