I've found a website to buy the true SAE, but they're recommending 1 per 5g.
This seems a bit much to me... I've got a 155g planted aquarium, so that'd
be an awful lot of SAE's. Right now, I've got two chinese algae eaters, a
pl*co, some pearl gourami's, rosy barbs, rainbow fish, diamond tetras, a few
mollies, and assorted small tetras. I'd like to get some SAE's and possibly
transfer one of the Chinese guys over to a smaller tank, but do I really
need 31??
