1. I don't have a source.. all of these were in a buddy's pond for over 10 years. They were all donated to me as he is getting up there in age and believes I will give them a great home.What a tank, man!
Four q:
-- What's your jullieni source, not SB but standard? I've been looking for a decade. Alas.
-- Is the dorado causing any issues?
-- Are you not afraid the little jullieni barbs may become food sooner or later?
-- Are you not afraid the pleco will scratch your acrylic or worse, it's been reported that pleco can wear out a large valley in acrylic when attempting to dig a nest?
2. None that I have noticed so far.. but keeping a close eye on that
3. A few of the bigger cats (Piraibas) will be moved to a bigger tank soon.. no real threats at the moment. The barbs are much bigger than they appear
4. I have never seen these guys on the side/front... tank is scratched up by the rays already
