I splurged today and bought some new plants (echinodorus blehiri) and a Marineland Maxi-jet 400 for my 30gal. I set everything up and left the room to let my loaches explore without interruption. When I came back a few hours later, I was rewarded with a delightful loach dance.
I was worried that the flow would be too strong, but everyone seems to be doing rather well. My danio were even doing some courting behavior that they reserve for the mornings that I change the water. I really want a camera so that I can photograph these fish, but all my money keeps going into buying things for them.
