Thanks Greg, much appreciated.
I've read that most Steatocranus typically breed around the same time as a thunderstorm or heavy rainfall. Their fry have a higher chance of survival as a result of all the excess nutrients and food that's washed into the water.
This sort of instinctual behavior is really interesting to me. Especially since they're able to still detect a thunderstorm or heavy rainfall in an aquarium, inside an apartment building. Haha.
