Yes. I looked at dried up sample I had. I need a fresh sample and will try
to get one again. When viewed under the scope the dried sample was football
shaped and quite small (cocci), almost the size of cyano's. I did see a few
small groups that might appear to be filaments. The drying could have broken
the chains that link them together but this seems doubtful. I need to see if
there are any flagella etc. So I need a fresher sample.

Well it doesn't care about soft or hard. That's strange the slow growth
building up.

Sounds like the same stuff.

Hummm... there's one commonalty.

Oh yes I don't forget them days. It would be interesting to grow in a say a
Tropheus tank etc. Fast food.

Pithophora is very pretty and makes excellent food for algae eating fish. I
used to use it in algae scrubbers and try to get a good growth of it on
rocks for fish to nibble on.
