Infurita thanks for sharing, we have almost the same growing conditions, though I have some Horse tails and cattails in my small container as "monocots" companion plants
I too have problem with U Gibba, in fact I hate them being in the same container as the Aldros as they can dominate the whole container, I had to tear them up to trim them off.
Why do you put Mossie Pellets in your container? Is it precaution?
The reason I ask is because I am 100% sure that Aldros can eat Mossie larvae. All my containers that have Aldrovanda, never, ever had Mosquito larvae in it. Aldros also eat waterboatmen beetles very well.
If you are up to it, try not putting any mossie pellets in the water and see if there are mossie larvae that will grow, chances are they will never reach maturity. My containers also do not contain any fish only plants and snails, snails also make good food for aldros. Never have had them flower myself and mine are all green
