Advice on Cichlids, new tank set up.

[Reecy]

I was in the aqua shop today and I asked the advice from one of the staff but just to make sure can you confirm.
I am soon to get a 4 foot tank and I am thinking of having Cichlids in there, I am under the impression they are aggressive and wondered what fish to put in the tank, the guy in the shop said they are OK with other Cichlids and large Catfish or Plecs but not other types.
I Like the idea of mixed Cichlids so I wouldn't mind going down that road, so is he right or is there some that don't mix that should be avoided, any help appreciated?

I guess that would depend on the type of cichlids you are talking about and the size of tank you have as well. A 4 foot tank could be anything from 55 gallons to 120 gallons.

Its generally not a good idea to mix cichlids from different parts of the world. Cichlids vary a LOT - angelfish are cichlids, as are rams; then you have Oscars and mbuna. You shouldn't mix any of the above. Apart from different levels of aggression, they also have different water requirements.

Pick a few favourite cichlids and we'll let you know if they will work in your tank or not.
