Hi everyone, I just put some turbo snails in my tank to eat all of the brown algae, that is covering almost everything in my tank, two days ago and none of them have moved (there’s 6) my water checks out and my salinity is at 1.024. They all appear to be alive but haven’t eaten or moved is there something wrong? Everyone else in the tank is doing fine, should I try a different clean up crew? If so what can I get that will be ok with a geometric eel and niger trigger?
