We got a sea hare to battle algae with us (9 month old tank with 65g display, 15g sump). It has been in the tank for almost 48 hours and while it has slurped the glass and sampled the rocks, I am not seeing a lot of change in algae. Even where it was on the glass it leaves little clean marks that look like deer tracks in mud, not like a street sweeper.
I am a little concerned that it does not like the algae we have - which is sea lettuce and mostly GHA (I think it is GHA, it survived a batch of reef-flux a month ago so I don't think it is bryopsis). I understand they don't live long if they run out of food so I want to understand if they normally take time to get in the groove of mowing down their veggies, or if we have a potential problem on our hands. I don't want to kill the thing - it is an interesting creature - so that's why I am wondering how normal this behavior is (do I need to intervene).
