Hello,

I have some Pseudomugil cyanodorsalis in my office aquarium. Lovely fish but they don’t spawn where they are supposed to: the mop. They would spawn in the fine Chaeto and other algae making egg picking a challenge. So I got some of this:

I made some mops and let them sink into the aquarium and fantastic mop full of eggs a few hours later.

Has anyone else tried this type of yarn for spawning mops? Has anyone observed a preference for these finer threads over the thicker yarn threads?

I am going to try this yarn with my Riv. cylindraceus and Fp. scheeli and see what happens. Sadly, no Aphyosemions to experiment with.
