Hi.
Anyone have an idea of these on the LR? I have read to many theories and still at a loss.

Thanks.

Good sign that your tank is doing well

These guys are part of the life stages of a tank. Almost every tank has these guys show up, sometimes in mass, and then they fade away. Either way, they are harmless.
