Update on our pond story:
The Gouramis have been very busy, there are babies of different ages all over the place, the smallest ones still being protected under the Lotus. You may NOT pull out a leaf or clean up some algae in that corner without having Daddy Golden Gourami firmly attached to your finger, as experienced by both of us!!
The Fish have really colored up nicely as expected and they are doing a good job keeping the pond free from Mosquito larvae and other bug-stuff.
I still feed them a couple of times daily, it is also a nice way to see them this way.
