mine is also finicky. when i got it, i got 2 frags, and 1 died immediatley. and i think i've given out over a dozen frags, and they have all perished at one point or another except for the frag gadgets now has.
the colony i got mine from also recently perished.
i've had my colony go through some STN events in which i was sure i was going to lose it, but somehow i keep bringing it back from death.
out of the past year, its only been happy for about 2-3months max...lol. i can tell it isn't happy as its just a drab brownish green color with light lavender tips.
