HK Pleco and Java Fern


A friend of mine mentioned about Hong Kong Pleco to clean the algae. Any
one on the list ever have any experience with it? I'm thinking of
trying it out but hesitate as it may eat my plants and costing 12X run 
of the mill pleco.

My new Java Fern has a lots of baby plants on one of its leaves. When 
should I remove them for planting. I need figures like how long should 
it get, the blade, roots and all. Thanks.
