They are nice fish
Your new one is a melanochromis auratus, often referred to as a 'golden cichlid'. from Lake Malwai. It is one of the most aggressive african cichlids around and requires a bigger tank that a 30G or there is a real risk it will end up killing anything you put in there with it...55 minimum, 75 preferable.
Your other one is a pseudotropheus zebra; also highly aggressive, also Lake Malawi.
You won't be able to keep anything alive in a 30 with that auratus. Mbuna, which is what your fish are, require a 3 foot tank minimum and 4 is much, much better.
If you can't get a bigger tank bring those fish back and try some Lake Tanganyikan cichlids instead -

My opinion is that Africans should not be stocked with a Green Terror although people try this and succeed. There is however no way you can put a Green Terror in that tank.
