Can Someone Tell me WTF these are?

  • We are currently upgrading MFK. thanks! -neo
So I have 7 Giant Danios in a 75 gallon with roughly 15-20 GT fry at around 2-3" and a young adult at close to 5"

and some of the eggs still made it haha.

now i hope they spawn again, is there things I can do to improve the probability of the danios spawning?
 
They are egg scattering spawners, so you need to provide places to safely allow the eggs to fall into. Some people suggest marbles as a substrate but that looks ridiculous.
