Yes, that is the dilemma! :-)

Try pieces of slate against the glass, and then move the pieces
periodically (rotating them to expose the mossy side, or moving them to
expose the growth on the glass). Not overly effective, but it does sort
of work.

I kept Otos well fed by rotating silk plants from other aquariums into
their tank.

Thank you - the idea about the other tank might work - though I've
only got one other - the 6g, planted... Hmm, I wonder what would
happen if I set up the 2g qt tank and put plenty of "mobile" surfaces
in there for algae to grow on... Maybe start it out with some water
from the 10g...?

I'll experiment! G
