Additional Information (No Pictures or Videos in the Section Please) Miscellaneous Information: the 14 young adult slugs were in my possession while Daniel Walden (waldend) was out of town on vacation. I returned the adult slugs to him and kept the egg strands for this rearing project. It seems to me that there is little need to keep large "broodstock" berghia if small adults will spawn with this frequency.
You will be required to provide photographic evidence in this thread of each event submitted for the MBI Program.
If your thread does not contain these photos the MBI Committee will not be able to approve your reports.
