We have a 5 gallon tank where we plan to grow hydra and we're trying to learn the best way to do maintenance before we start our process.

I don't have direct experience with this, but friend of Public Lab, @jholmes5 turned me on to the Amateur Microscopy group on Faceb00k (https://www.facebook.com/groups/Amateur.Microscopy/), and I've found that to be a pretty knowledgeable and supportive space (as these things go). Could be worth a crosspost?

Thanks for the suggestion Bronwen! I cross-posted there and here are some of the responses:
Delta M: I regularly have Hydra in my fish tanks. They come with wild caught live food from nearby ponds and steel the food from my fishes. Several species reproducing in large numbers as long as they can catch living Daphnia or Cyclops.
They don't care about the tap water I use for water changing weekly around 90%. To break down the population it takes several weeks without live food.
Steve S: Hydra can be easy to grow. I never changed water, or aerated, or specific light. They did need to be fed (Daphnia is best) but the danger was over feeding and having a Hydra population explosion. I published a couple of papers on Hydra and kept it as simple as possible.
Khoroshyy P: I have a 20l aquarium, with some plants. I set it up in the begining of summer. Never changed water. After some month, I inoculated some pond water and some algae and invertebrates. I really don't do anything with it. No feeling no cleaning. But there are plenty of Hydra viridissima on its walls....
But if you want to change water if can be syphoned out... They will survive a couple of minutes on wet walls...
