I posted the pictures in a previous thread about blackworms here: http://forum.nanfa.o...h...ost&p=33686
Jase - I'm looking forward to it! Do you know if blackworms require sand beds to thrive? The substrate in my tank will be variously-sized gravel and stone; there may be some sand, but not extensive areas of it.
I'm pretty sure you could get them to live in gravel, but I doubt you're going to maintain a population in a tank with suckers. I'd keep the blackworms separately, and just add them to the sucker tank when you feed.
