Great pics! So interesting how different in coloration our mokes are. They're easy to tell apart.

as usual. 
Just get more plants. You will have algae from time to time. That's just life underwater. When you have more plants it's not as big a hit to take some out, trim leaves, etc. I personally like some of it because it adds to the effect of a natural habitat. Plants in lakes and rivers grow algae. I'll show you my 20 long, hold on.
