James rang with the news. Before, it was more like 5.0. Hooray! This is a very exciting thing indeed. He also said that even though he had fed them in the morning, when he stuck his arm in to replant something all the fish were swarming around and looking for food – so he fed them again, and they devoured it quick-smart. Apparently there is meant to be a change in behaviour when the nitrites go down, so it seems like our fishies are a little bit happier!
There is virtually none of my succulent-looking plant left: rotten little buggers have eaten almost all of it. Grrr.
