The tomato clowns in my school’s main tank have decided to lay eggs. I was going to try to catch them in a homemade Vossen trap, but I can’t seem to find anyone who has rotifers. I would need them soon, so shipping is out of the question. Does anyone in the greater Philadelphia area have a culture of rotifers going? I’d like to try to start one and see if I can get a few of these baby clowns to survive.
