angels are cichlids the thing about cichlids is they can be agressive and they can be territorial, it ranges from species to species though. angels can be ok, some are nasty and some are placid as except for breeding. all breeding cichlids practise parental care and thats when their nasty nature can come out :lol:
it depends what type of cichlids you want to keep. angels are generally ok for fish that dont have long fins. like all fish if it can fit in their mouth theyll eat it, and it very often happens with them and neons. a few of the other commonly kept cichlids are rams, discus, kribensis etc. im not sure of any sites that could give you some pics of different cichlids but it would be worth doing some research, you want fish that are commonly placid if theyre to be kept in a community situation.
good luck choosing your new fishies
