Info from Japan

I received the following from an acquaintance in Japan (who I'm 
trying to convince to join the mailing list):

> From: Shinji Egi
> At the beginning of this month, I had a chance to go to the shop which
> deals with the Amano's [author of _Nature_World_Aquarium_] products.  I
> checked that the question about the water circulation in the substrate
> which I mailed to ADA last year had been ignored.
> I found that Amano wrote in one of the Aqua Journal the story of
> discovery of the Yamato-numaebi as algae eater.  It goes:
> He noticed that some shrimps do pretty good algae-eating job.  So, he
> asked an dealer to gather all the domestic shrimps and crayfish.  And
> tried all of them.  He set some checklist to evaluate them - such as
> algae-eating efficiency, compatibility, ... 
> Yamato-numaebi was almost entirely satisfactory.  Amano asked the dealer
> to gather as much Yamato-numaebi as he can.  The dealer was doubtful
> that the shrimps sold well.  But, Amano was confident.  And today,...
> So, at least Amano says that it is he who first intrduced that shrimp
> as algae eater.
> By the way, I've got 15 bee-shrimps at that shop.  They are about 1cm
> long now.  I think they are not so sufficient algae eaters.  Probably
> a Yamato-numaebi worth 5 or so bee-shrimps as algae eater.
> I'm going to keep the bee-shrimps anyway, since I need algae eaters
> compatible with small killifish which seems not compatible with
> Yamato-numaebi.  I would breed the bee-shrimps and see if they work
> well when the population gets huge.
