Hi. About a week ago I got a new wave-maker powerhead which made the feather duster blow like long hair on a windy day. I thought it would like that since it is a filter feeder. I was wrong. Today I found it's head had blown off onto the sand. I planted the head by securing it in sand so it doesn't blow around and moved the worm casing rock to a low flow area. Does anyone know what I can expect now? Is the head alive? Is the worm hiding in its casing? If so how will it get any nutrients? Thanks in advance for any advice I receive.
