So, you say, you want to start keeping cichlids? Eh? You want some that are peaceful you say? And small? And easy to take care for?

Well, welcome to the wonderful world of ram cichlids!

~What is a Ram Cichlid?~
Rams are fish that belong to the genus Mikrogeophagus. Literally translates into "small earth eater" I believe from greek [or latin], Mikro translates to small, geo to earth and phagous [nope not a typo] to eating. These fish are what their genus says. They uptake mouthfuls of sand into their mouth and filter it through the gills, or sift it in their mouths, hence "earth eater", to find bits of food leftover in the sand. Very cool to see. There are only 2 fish species currently described in the genus Mikrogeophagus, and they are the Bolivian ram, M.altispinosus, and the German Blue Ram, M.ramerizi . You may come across names like the 'red ruby ram' and the 'butterfly ram', those are just more names of the two species. Both species max out at about 3 inches for males and slightly smaller for females.

~The Bolivian Ram~
Ah, the Bolivian ram. My favorite out of the two species. The Bolivian ram's colors start on a brown or tan base and build up with hints of blue-green and a black dot on both sides of the fish.

The Bolivian ram is a very peaceful cichlid that is although it does not boast as much color as the German blue ram, it still has enough color to compete with apistogrammas, showing off the bright sunny orange when in breeding dress. They will follow you as you pass the tank and will beg for offerings from the little tin that has granules of whatever food you feed it.

Bolivians are said to be much hardier than German Blues for the reason that they are less inbred than German Blue Rams.

And surprise surprise! This ram is a subtropical cichlid, with preferred temps ranging from 74-78.

Males will never fail to bore you as they spar with each other rarely causing damage and competing for females, and often two males will end up in a lip lock over territorial disputes, and the loser loses the prized territory.

This spectacular, personable and hardy cichlid is almost always the way to go when starting out with cichlids. They will never bore you.

~The German Blue Cichlid~
Obviously one of the most colorful freshwater fish on the planet, the colors are shown on german blue cichlids are rivals to marine life with all the colors of the rainbows on it's side. The German Ram often commands a higher price than the Bolivian, for the fact that it is much more sought after than the other counterpart. This species is a lot shyer and prefers to be in groups. best to build the tank around this fish, and stock it with slower, smaller fish. Even with it's shyness, in the right conditions, it can the most active fish in the tank. Males will court females and the breeding dress of this fish is spectacular during the performance. This fish is also a common tankmate to discus.

There are several different phenotypes of this cichlid like the purely dark one, the gold ram, the electric blue ram and very unheard of, the red headed gold phenotype which I would love to get my hands on. There are also some body morphs like veiltail and ballon rams.

This cichlid is at the other end of the temp spectrum than its cousin, and it prefers waters over 82 degrees Fahrenheit which seriously reduces the compatibility of this fish with other fish. These fish also have the reputation of being picky eaters, sensitive and fragile, which can be true on occasions but can be completely ignored if you get your fish from a reputable breeder.

~Venn Diagram Without the Circles~
Bolivian Ram- Hardier, cooler water fish, less colorful, active, not shy, will take most prepared foods, less sought after

German Ram- Less hardy, sensitive to sudden changes, shy, extremely colorful, energetic, willing to breed, tons of color morphs, hot water fish, more sought after

Similarities- Personable, stunning in breeding dress, readily adapts to different waters, both pit spawners

~Which Should I get?~
Depends. Looking at cichlids for the first time? Try bolivians. A bit more experienced? Try GBR. Both are fairly hardy cichlids and both are beautiful under the right conditions. Consider temperature when incorporation these fish into a stocking plan.

~Final Words, then Adios!~
No matter which one of these fish you decide to take under your wing, you won't regret it. They will shed a whole new light how you see fish, and they will never fail to amaze you. Both of them are showstoppers at color and will never bore you. Whichever one you choose, remember to do research and consider temperature when stocking your aquarium.

Feel free to contradict me if you think anything in here is wrong at any level.


¡Adiós!
