I have to admit I think some of the guides that you are looking at are a bit on the steep side....
Personally I think your set ups are fine as they are...
Rams are a small cichlid and can be kept in my opinion upwards of 65/70 litres with little or no problem. Their territory patrol is not that big and most 18inch square to 12 x 25 inch squares - most breeders wouldnt keep them in anything else. Since they are the only cichlid in there I would say so long as their tank is complex and interesting for them to sift through they will be very happy. The bigger issue is how they are coping in the water you are keeping them in, they are sometimes tough to keep depending on their lineage - ie if they are quite close to wild fish they need high temperatures and low ph where as more intensively farmed fish are better in mid temps and mid ph. How long have you had yours and how are they doing? Are they active? Well coloured? Feeding well? Are they interested in the outside of the tank and do they interact with you when you approach the tank?
Khulli Loach - I think with just 2 the tank will suit them, loaches are gregarious not shoaling so its not truely vital for them to be in large groups though it is preferable and will encourage them to come out more. I think because of this 2 will do well in your 10g as they are not that active and again for me have been a popular choice for smaller tanks like this...
The thing in this tank I am a bit concerned about is actually the Cories... they are actually a schooling fish more so than the loaches and need to be kept in at least 6 - this is to replicate the view for the fish of being in the very outskirts of a large school, when the need for feeling safe in a school is needed.
I mean saying that the fish above will be okay in the smaller tank they are all fish that are really on the brink of being okay admitedly....
One option you could consider and Im not sure how you would feel about it but you could change your schooling fish from the Tiger Barbs for something less fiesty and a bit smaller and add some of your fish from the 10g into the 30g so your stocking would look something like
2 Kribensis -1m1f
1 Blue Ram
2 Platy
8 Flame Tetra? Lemon Tetra? Flame Back Bleeding Heart Tetra?
1 Albino BN Pleco
6 Corydoras - since you have Albino you could do a mix of Albino and Bronze as the commonly available Albino are the Albino strain of the Bronzes
OR
6 Khuli Loaches
Then leave the 10g free for a new community - in small tanks I really think the best way to go is micro fish like galaxy rasbora and pygmy corydoras.
Hope thats helped...
