WOW! Absolutely incredible!
It is not uncommon for them to split into 3. I looked over WetWebMedia a few weeks back, and one guy was cultivating rose BTAs in his 175gal. He would not feed them for three months, then on the fourth month feed mysis 3 times weekly. At the end of the fourth month, he did a 40% WC, then one week later another 40% WC.
I'm not sure if this works, but if you want them quickly, this is a possible route.
Or you could just continue your current nourishment.
Good luck, and congratulations.
