Red Seaweed for sale

June 8, 2002
From: Jim DeMattia

Hello,
My company Aquaculture 101, cultures red seaweed (Gracilaria pacifica,) which is a great feed for many marine slugs, currently we sell to tropical fish companies and some researchers working with Aplysia californica. I am located in San Diego, CA.. Please email me for more info and prices, we will beat any prices from Florida.

Dear Jim,
I don't usually post advertisments for the aquarium trade but your message gives me a chance to reply to the misinformation which the trade is spreading either through ignorance or design. To say as you do that red algae is a "great feed for many marine slugs" is incredibly misleading. As far as I know ONLY Sea Hares, such as Aplysia, will eat it. Other herbivorous sea slugs, such as the sacoglossans, each have very specialised diets, and as far as I know none feed on Gracilaria. Most people who want to keep sea slugs in aquaria, want to keep the bright colourful nudibranchs, and ALL of those are CARNIVORES, quite unable to and quite unwilling to eat Gracillaria or any sea weed, no matter how juicily prepared.

Please stop perpetuating this myth that nudibranchs are easy to keep in home aquaria, because they feed on sea weed. It is untrue and is encouraging a trade which can only help destroy tropical environments and starve many nudibranchs.
Best wishes,
Bill Rudman
