so I have reached the brown ugly stage I have a few snails but they need back up !!!! ( wonder if a snail will gorge himself to death ) anyway I have always liked Red Banded Trocheus snails since they readily reproduce in tanks . But I am a big believer in variety and biodiversity And I also believe that should start from the micro fauna up , bacteria , pods snails crabs ?? then fish as a complete clean up crew . Sure I like ornamental fish but "worker" fish to me make more sense . So lets hear some suggestions and help me pick my livestock for my 75 gallon
