My tank was literally infested with brown algae. I bought 5 ottos to take
care of the problem, and they have done a remarkable job over the past 5
days. The glass is now almost spotless, but fine leafed plants such as
hornwort and java moss are still very much covered with brown algae. Both
plants are actually growing wonderfully, especially the java moss.

In your experiences, will the ottos move on to clean up the moss and
hornwort or are they likely to go for the discus slime soon. I've got the
zuccini ready for them, but don't want to introduce it too soon as I'd
prefer them to clean up the 2 plants mentioned. I definitely want to keep
these little guys happy, as they have been a great asset to me. I just
don't know how far they'll go to eat brown algae (their preferred food?).

Any advice or tales of experience would be appreciated.
