The water flow is moving from left to right (relative to the picture) so there is no direct flow going straight into the head. They used to be up on the top level of my rock work and flow was quite heavy there. Since then I have moved them down to the bottom level of the tank where the flow is moderate. Since I have placed them lower in the tank the exoskeleton has started to disappear more but it has its good days and bad days.. Should I try moving them to an even lighter flow area? Or are there any dips that may help nurse it back to health?
