Bolivians prefer a planted tank with low light levels, driftwood (territorial markers) and lots of plants. They can be kept in pairs but show interesting social behavior in groups of 5 or more. Each fish should have at least a 10" square territory. Many consider "Bolivian Rams" an excellent choice for a South American community tank. Undemanding in regards to water chemistry, small enough to be kept in smaller aquariums, brave enough to be kept with larger fish. Their outgoing nature and eagerness to greet their owners make them very popular with aquarists.

    My new favorite fish!

    Posted by Zoltan Hajdu on 23rd Mar 2015

    I have ordered four of these for a 20 gallon high tech planted tank. They have arrived healthy and curious, they immediately after the acclimation started to map their new home. Initially they where sticking to each other, but after couple of days each of them have found a spot. Now I only see all four of them at feeding time. Regarding the feeding, they are slow eaters, I had to remove some adult platies and guppies to allow them to get to the food. These are really cute fishies with a great personality!
