I'm not tryin to make you seem like an idiot Bass, but when you get advice given to you, and then go do something even though it was advised against it gets kinda fusterating. Now as for the space issue, I have tried keeping two pairs in a 40gallon breeder sytle aquarium, 36longx18inches wide= 648square inches/ 144 (inches in a square foot)= 4.5 square feet, a 55gal is if I am not mistaken 48x13=624square inches/ 144= 4.3 square feet, a little less than the 40 breeder. The rams simply would not coexist together in that 40breeder, one pair dominated the other, who then went hiding, wouldn't come out to eat for fear of being beat on. I simply moved them back into the 20 they were in and all is well again. I would really only suggest one pair in that 55. 10gallon tanks are very suitable for a pair of rams, and they are perfectly happy in there. They just become too aggressive with each other to keep more than a pair in a tank less than I'd say a 90gallon. Trust me I've tried a couple times to get both my ram pairs to coexist in the 40gal and it won't work. If you can only have two tanks, and want to keep both golds and blues, then take a gold male and female, and a blue male and female, put one pair in the 55 and one in the 20. They are great and peaceful fish with their other tank mates, except other dwarf cichlids, they inhabit the same area as the rams, look for the same structures to establish a territory, and thus are seen as a threat. When I got both my czech bred german blues, they were about 2months old, just starting to pair off, they were fine in the 20gal together for a while, about a week, and then one pair took over the tank beat on the other, so I had to move that pair into a 10gal. Since then the pair in the 10 has been relocated into the 40breeder, I tried adding the pair that was dominante in the 20, into the 40 and they got beat on. I won't say its not possible because I am sure it is, but you need to have the right fish, with the right conditions for it to happen. I mean Puma and I had 2 male bettas and 3 female bettas in our 75gal, all of them shoaled together which was odd, and every week or so one of the males would spawn with the same female every week. Everyone was fine, no problems at all with keeping them all together. I do not advise trying that, we got lucky with our expiriment. Strange things do happen, just they aren't common.
