I have a 75 Gallon that I've been randomly breeding guppies in for several months. a few months ago I added four corydora catfish. I found these on the fake bamboo leaves I have floating in the tank. does anyone know if they are eggs or a possible fungus or something? one extra note: my oldest and biggest female guppy died randomly last week, but I haven't had any other casualties. they get regular water changes 30%/wk, and nothing alarming has been noticed on my api freshwater master kit. it is filtered with two 4" sponges each attached to their own 250gph powerhead. tank temp is currently 76.2, but fluctuates between 74-78.
