Redfin Prochilodus (Silver Prochilodus)
Originating in the Amazon basin of South America, the Redfin Prochilodus is a vibrant fish with a bright silver body and large eyes. Its caudal fin features alternating black and yellow stripes, and its pectoral fins are a striking red. This species adds visual variety to an aquarium and helps control algae due to its herbivorous diet.
Requires a minimum 70-gallon tank with a sandy substrate. Provide ample hiding spots using driftwood and rocks. The fish is generally peaceful but can become territorial, especially as it grows. Compatible tank mates should be similar in size. Avoid delicate plants as the Redfin Prochilodus may consume them.

Added a few Redfin Prochilodus to my 80-gallon tank. They look great with the sandy bottom and driftwood. The fish are active and help keep algae under control. Only a few hardy plants survived, but that’s expected. Peaceful overall, though they did show some territorial behavior when two were placed close together.

First time keeping this species. The red pectoral fins stand out in the tank. I’ve kept them with larger, calm fish and they haven’t shown aggression. The tank needs a sandy base and plenty of hiding spots, which I’ve provided. They eat algae regularly and don’t seem to harm the plants.

The fish arrived healthy and look nice in the tank. I’m not sure if they’re eating the plants I added, but they seem to be active. I’ll monitor their behavior over the next few weeks. Tank size is adequate, but I wish the instructions were clearer on plant compatibility.
