Those are my P Horrida too mate and I do the same with my Biggutus
I've also got about 400 Mombo eggs (from 3 adults 1 male 2 females) but nothings hatched yet and I've no idea why and they're my favourite
I moved all the nymphs in the pic to rearing tubs and counted 209 and I already had another 150 so they're pretty easy to keep -breed - rear
I'm about to get some P Rads as well then I'll have the set of 4 I love all the assassin's very active and interesting to watch great display species and I've been amazed at what size prey they'll take when I had nymphs in the main colony I put all sizes of Roach from tiny nymph to adult and the new Horrida nymphs were taking sub adult lobsters

the adult horrida take adult male dubia easily so luckily I always have loads available as I use them for a lot of my Ts as well
