Ordering Full Grown/Near Full grown Cichlids

[Swiler123]

Does anyone know a website that sells almost full grown South American cichlids? I have a 300 g tank and it needs some fish but they need to be full grown with what is already in there. Any help is appreciated!

I'm from New Zealand so can't help with the question. But I'm curious what is already in your 300g, can you put up a photo please?
