Did I see the word "never" in your post? Oh oh, you have jinxed yourself now. I have a fern and a short piece of pothos plus a piece of spaghum. I took out the coconut hut. I plan on buying at least two more D. auratus from the same dealer to make a group. You are right in that the small tank is not very secure (a cover problem) but will be getting a better setup soon. This forum has been such a good source of info. Thanks to all.
