Well it looks SLIGHTLY bleached, so i can't tell if its on the mend or getting worse. Make sure to monitor that, if the tentacles become more clear, additional lighting may be necessary.
Feeding, that nem looks pretty happy (sans possible bleaching) so feeding may not be needed, but would be appreciated. IME, if you feed 1-2 times a week, your bta will get big. If you feed 4-5 times a week (SMALL meals) it will split more readily. Again, just my experiences from my BTA prop tank.
