I would really like to add some gold ring loaches (sewellia lineolata) to my 90 g tank. The tank is on the warm side 80 to 85. I know these guys like well oxygenated water. My school or roseline sharks are thriving and they also like highly oxygenated water too. The tank is highly planted and has CO2. Think it is worth trying? I have seen at least one other member here comment that theres is doing well in a warm discus tank.
