I would suggest more plants and don't disturb your gravel (like thru
suctioning). The black stuff is probably a cyanobacteria. I have a couple
of bare tanks with this in and all I do is regularly siphon the gunge off
the sides when it is looking bad. In the worst case, I move the fish to
another tank and strip the old one down but otherwise the fish do fine.

As for the green thread stuff, apparently siamensis (flying fox catfish
types) eat it. But mine don't. I just keep ripping it up until equilibium
is reached. I only have one tank with this stuff in it now, and it keeps
reoccuring around the same spot, so ripping it up isn't a big drama.

As for plants, go for some sword plants (melon swords are a personal fav.).
They are fairly robust and do a good job of outcompeting my algae for
resources. Mind you I do have a few (like 20) in the tank with the green
thready stuff so perhaps more elodea or cabomba etc. would be better.

Anyway, there are heaps of plant people on this list.

Good luck
Graeme
