First, may I welcome you to Tropical Fish Keeping forum. And to this wonderful hobby.

I think you may have some issues with this mix of fish in (to them) such a small space. The Golden cichlid is presumably Melanochromis auratus which is very aggressive. The Blue dolphin Cyrtocara moorii attains 8+ inches and is by comparison peaceful but need a much larger space.

Our member Tazman can elaborate, he has considerable experience with cichlids.

Next issue is cycling, is this tank cycled? Of were the fish added to a new setup? You can read about cycling here:

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
