That looks good, but zebra plecos are extremely rare and expensive, often selling for over $150
Bristle nose plecos or peckoltia species would make better choices

Aside from a certain minimum for security, the choice of how many is largly personal taste. I like big groups when it comes to schoaling fish, and I wouldn't hesitate to go with 20 hatchets since you have the entire surface free, and 6 silver dollars (but I'd be enclined to start with more, as they'll be a little lost if you are getting them young).I'm not exactly sure how many of each species of charicans to add, any suggestions?
I'm a little biased on it - I'm simply not into tossing a bunch of aggressive fish that are naturally enemies into a tank together.
I've always thought of shoaling fish and fish gathered in groups as the same thing (they stay in a group, but don't necessarily swim in unison at all times)freddyk said:Consider getting 6 or 7 Heros with the intention of ending up with a couple of pairs. The Uarus aren't schoaling fish, but they do live in groups, so a group of 4 of them would be nice.
I'd certainly leave the pulcher out of it, these little guys probably won't be thrilled sharing a tank with so many large cichlids.
