As far as I know, our second batch of upside down jellyfish is still alive! This is the 1 month marker. We've also managed to take some data on the flow fields around the bell as they contract using piv (particle image velocimetry). The big problem is controlling the algae in the tank, but we've ordered a protein skimmer (to remove the debris the algae eat). We will need to redesign the tank though with a separate compartment for all of this filtering.
