I bought a Bolivian Ram for my first aquarium and it has been thriving for over six months. The fish is very calm and colors look vibrant in the light. It doesn’t stress other fish in the tank, which is great for a new aquarist like me.

The fish arrived healthy and looks exactly as described. I keep it in a 20-gallon tank with some plants and it’s active but not aggressive. Water parameters have stayed stable since adding it.
