Thank you mighty master of the threads! I currently have a batch I raised individually and all but 2/12 have morphed. There were some more available to me to rear but I lack the time I had before and was just fishing for info. Was hoping to do a heavily planted communal set up but looks like I'll do the "corral" method I used before. Better safe than sorry. The individual, no flow, cup method scares me. I need filtration to feel secure about nitrogen product spikes. Still have my rearing setup running, I'll just stick with it. Thank ya sir!
