OP; your stocking's not to my liking; I'd have put only one species (either a pair or a trio) of cichlid in there; I think that amount might cause you big problems in the future. The kribs are almost certainly going to be too big and bolshy for the rams, for a start.
They're all pretty territorial, even peaceful cichlids need their space, especially if some of them decide to spawn.
I'd have stuck to a larger number of one species of shoaler too; the fish are much happier and you get a much more impressive, natural looking display.
Arent those frogs advised to not be put in tanks that are normal or tall cuz they have a hard time swimming to the top to get air all the time? I thought I read you need a lower water level for them. Something to think about/research
The dwarf frog should not be in water deeper than 14" - there is a greater risk of stress/illness and eventual death from having to constantly struggle up for air.
Also, I do not recommend them being kept with any species of cichlid
