So I currently have a 75 gallon tank with 3 eb acaras, 2 eb dempsey, 1 firemouth, and 1 rhino pleco, I was wondering if I could get another catfish. More for cleaning up leftover food and to look neat, since I've seen several that are best looking. The ph is around 7.8-8 and I keep the temp around 79-81. The tank is cycled and been set up for 3-4 months now. Every other fish is around 3-4 inches. If anyone has any ideas please feel free to let me know!
