Hypselodoris bullocki Egg Ring

January 24, 2001
From: Cindy Luczkow

Hi, I just purchased a Hypselodoris bullocki at a Fish Store in Southern Oregon, not realising how difficult it is to sustain. I do have some sponges in my 72 gallon reef tank but whether they are of the right species, I don't know.

Upon introducing it into my tank, It formed a yellow ringed egg sack ontop of an astro snail.

What do I do next? I hate to be the cause of these little guys dying.
Help!!

Dear Cindy,
You are not the cause of them dying. Blame that on the people who organised to ship them to the USA then conned shop owners into stocking them and customers into buying them.

There is a slight chance that you have a sponge in your tank that Hypselodoris will feed on. I don't think there is much point taking it back to the shop because they won't be able to feed it either - although it might teach then that they shouldn't be stocking them. As to the eggs. The eggs will hatch as little veliger larvae that will swim in the water looking for planktonic algae to eat. If they escape your filters, and find the right algae to eat they might survive, but unless you have the right sponge, there is little chance they will take the next step and metamorphose into a baby slug.

Sorry I haven't better news for you
Best wishes,
Bill Rudman
