The first ones that would jump straight to mind are Madagsacan rainbows which are stunning fish, Paretroplus maculatus, Paretroplus menarambo even six species of Malagasy crayfish.
The problem is that the native species are under serious threat because like everywhere else introduced species like Channa, Tilapia and Gambusia are decimating native populations and areas of native vegetation are been removed for rice paddies causing loss of habitat, its amazing how much isnt shown in programmes like this /mad.gif" style="vertical-align:middle" emoid=":mad:" border="0" alt="mad.gif" />

The program did mention this, about the rice paddies, stating it was fracturing the forests making separate islands. It's sad, especially when people let loose with FMD's (Fish of Mass Destruction).
I'm guessing the rainbows are due to being originally part of Gondwana?

The paratilapias are an interesting group of cichlids.

The Beeb seem to have a blind spot when it comes to fish in general, unless they're being eaten by something else.
In the case of the Rainbows, previously it was assumed that it was due to colonisation by an oceanic atherinid ancestor but the close relationship with Melanotaeniids is now taken to assume that it is from a Gondawanan distribution.
The alternative would I think indicate that there was a marine ancestral group to both Melanotaeniid and Bedotiids that subsequently had the bad luck to go extinct right across the Indo-Pacific.
