Update: The eggs appear to be viable!!

It took a while for the mods to approve the post, sorry for the delay, here's how I accomplished this:

Habitat: The basis of their setup is a 250-300 gallon aquarium in my backyard (I live in Northern California) with a mesh top. The tank is covered in very densely planted Water Hyacinth & Water Lettuce with water lily tubers on the sand substrate. The eggs were deposited in the roots of the water lily, entangled in peat from the hyacinth. The tank notably has a slow leak (slower than evaporation) and is often just a little over half full with hyacinth roots reaching ~12 inches down to the sand. The sirens primarily eat the vegetation, but I throw in sinking pellets and feeder goldfish from time to time. I also have 2 small (rated for 50 gallons each) heaters in the tank set to 55, just to ensure it doesn't get too cold and freeze over. Some interesting things I have observed are that they do engage in biting behavior as a courtship mechanism. The male seems unharmed, however the female has 7 or 8 bite marks along the side of her body, with a couple of them lightly penetrating the skin. She is being observed closely to ensure her health, and I have a water tank ready in the event of an emergency separation. I have also observed both parents tending to the nest. Interestingly, the male spends a majority of the time coiled around the nest as opposed to the female, which is notable as I have read that the female typically guards the nest.

The eggs only showed signs of viability today, approximately 5 days after they were laid. The eggs that are developing are part of the batch that I separated from the nest for close observation. It is difficult to see into the tank, but I will report more info on how the eggs in the original nest fare compared to the separated ones.

Let me know if you have any specific questions? This has been an amazing experience for me and I would love so spread any and all knowledge

Hey all, just wanted to update! Its day 13 and a vast majority of the eggs are doing well! Eyes should start forming soon =) maybe 15 duds so far, but they are extremely easy to spot and remove without hurting other eggs.
