Yellow Lab friends?
I have a 20L with one adult yellow lab, one Cory cat and an algae eater. What else can I put in the tank? The lab appears to be female. Originally, I had three, but two have passed away over time and I'd like to give my last lab some friends. I doubted I could get any other labs for the tank, and I realize that, due to the tank's size, I can't put a lot in there.
People who say that pets lower their blood pressure never had a reef tank!
