not sure if this is the right place for this since it will not reproduce, but it can be passed along to fellow reefers in need of algae control. this sea hare was purchased a couple weeks ago and has done a great job on my green hair algae and red cotton algae. it is about 4" and burrows itself in my sandbed just before the lights go on and comes out at night to feast. rules: 1. you must be a BAR member. 2. you must be able to pick up from my place in sf. 3. must bring your own container. 4. must give me priority if i need hair algae removal. 5. must have >-5 dbtc karma. 5. pick a number between 1-10.
