I don't think so. Substrate or water column as long as they have nutes
they do ok. Thomas pointed out - and I forgot to - they like it cool,
lke 72 max. I've never had any luck groing them in the high 70's.

I think that's what happeened. I've grown them in manure and they
didn't rot, so I doubt rich substrates cause them to rut.

It's an abondoned 15 gal tank my daughters goldfish was in. Nothing
special. The more I think abiout it, as long as they're kept cool
they should thrive in just about any conditions except total darkness.
