  With this set-up you could safely add a number of other Cichlids which are colorfull and generally peacefull to each other. Of coarse the number and size of fish would depend on your filtration type.

• I recently came back from vacation to find my black molly dead and half eaten. Why would my other fish eat the molly?
  
  Most fish will consume the dead remains of fish in your system. This may seem disgusting but in all actuality is helping your systems health. Rather than the fish rotting away in your tank is is effectively being disposed of naturally.

  Yes this is common for the barb species, they tend to be a little aggressive towards their smaller, non barb, tank mates. One good match for barbs (especially tiger barbs) are clown loaches.

• I have a 10" arowana. It was attacked by the crayfish in the tank. It is missing scales and is laying on the bottom. Do you think he will make it?
  
  If the arowana was healthy prior to the attack, he should make it. Make sure there is nothing else in the tank that could show aggression towards him in this stressed state.
