Beautiful pic Vrae! U.humboldtii has always/will always be my favorite plant. How did you manage to keep it alive with just water apart from the fact that it killed your bromeliad with algae? Ive always tried to grow it using pure water but it always rots and dies. Did you use peat or sphagnum?
I actually did once try to grow a U. humboldtii inside a bromeliad. The utric started exploring and growing, but it was fatal for the bromeliad. Slime algae contamination from the source material of the utricularia grower who gave me the plant completely choked the bromeliad. Since the centre is the growth point for these plants, if it gets choked with algae, the bromeliad starts a steady decline. No matter how hard I tried to get rid of the utric and algae, it was all in vain. The algae would always come back.
