Is it true that Bolivian Rams are easier to keep than Blue rams?
Are they less sensitive to water conditions?
this is from
http://www.skepticalaquarist.com Cichlid section:
"Microgeophagus altispinosus (Bolivian Ram). (Though you see "altispinosa" everywhere, surely it ought to be "M. altispinosus," no?) M. altispinosus is a bigger, sturdier Microgeophagus, that gets to 4 inches (the female staying somewhat smaller). Fishes have red upper and lower margins to their tail fins, which are extended into filaments in the males. Otherwise they're a greenish gray with gold and black, less colorful than the domesticated Rams, it's true, but healthier, for the time being, and less inbred.
This fish is found in Bolivia, in the Rio Mamore near the town of Trinidad, in the basin of the Rio Guapore down to its mouth, in the Rio Quizer near San Ramon, at the mouth of the Igarape, and near Guajara-Mirim on the Brazilian border, according to H. Richter, 1989. This fish was discovered as long ago as 1911, but it wasn't represented in aquaria til Horst Linke and Wolfgang Staeck found a few in 1985 and got them safely back to Germany. These fishes are uncommon in their native haunts; the ones you'll see at the LFS are bred in Singapore from stock that originally came from Germany. De-worm them when you get them into yourquarantine.
It's worth repeating the water parameters Linke and Staeck reported where they found their fishes: pH of 7.6, KH about 4 degrees, with a conductivity of 123 microSiemens. Noonday water temperatures hit the equivalent of 81oF. In other words, if you have trouble getting your water acidic enough to successfully spawn M. ramirezi, you might have better times with M. altispinosus . Give these fishes shade, perhaps from some floating plants, and plenty of cover. If they seem shy, it's a sign that light is too strong and perhaps the tank is too bare and open."
