I am going to plant it with the Appleblossom, it blends in so well with them. It kinda sticks out because it towers over them, and the blooms is so much larger. I have spent hours trying to find it's name, I now believe it's an albino appleblossom. Barbra

Dave If the leaves are super smooth (as you said in another post), and they are 'creased' and firm, I would say it is e. runyonii Topsy Turvy. I am not sure because the flowers should be hanging down, and flower stalk slender, with smaller and more spaced-apart leaves. Maybe it's so compact & bigger leaves because of your growing conditions? But photos I have seen are much more like plant I am showing. Hopefully, someone more knowledgeable will chime in... Rina

Congratulations! It is Pompon de Paris CL. I thought I had lost it but it is coming back really good this year.

"seriously overcrowded"? If you havent checked ammonia/nitrite/nitrate levels pls do so asap - water quality is always the first thing to look at. It can look ok but be seriously toxic. Also - what is your water turnover rate - gallons per hour - not what pump is rated for but the actual rate. Your set up should be such that the oxygenation is plentiful - no matter what the temp or whether its day or night. These would be the things to start with.
