I like it as a feature plant, but if you want a carpet its brilliant
Got some sweet tools from Aquarium Plant Food UK and I have to say it's great to plant things and have them not get yanked out immediately! The finger holes on the scissors are also rounded instead of flat so they don't dig into your skin. Pretty good value too, £25 for everything pictured.
Removed most of the pearlweed and replaced it with Hydrocotyle Tripartita since it was clearly struggling. Also added Dwarf Hairgrass and more detail stones to the foreground. Weirdly, I must be the only person in this forum who is hoping it doesn't spread, I just like the little tufts.
