Hi. We are relatively new to having a tank and crayfish. So naturally one of our crays laid eggs not too long after we got everything set up. She has been diligently fanning them and keeping to herself. She laid her eggs on 8/27 so almost we are going on the 5th week now. They have grown fuzzy and the eggs that are still visible haven't changed in appearance. Do the eggs have a fungus or is this something worse? What can I do to help her (and the rest of our tank). Will this spread? Any advice would be appreciated. We are also battling some brown algae (diatoms?) right now that we are working hard to keep under control. Thank you!
