Hello, I was reading in the archives and found some posts saying that ghost shrimp and rainbow shrimp will eat hair algae. My LFS has ghost shrimp and mole shrimp. The ghost shrimp they have are very tiny (I think my apistos could eat them, or at least rip them apart). So although they are cheap, I am afraid that they might not last long enough to eat the algae! (How long do they live anyway?) The mole shrimp are brown and much larger, so I would rather get them if they will work. Does any one know if the mole shrimp will eat the hair algae? What is the cause of the hair algae so I can avoid it in the future? I have a planted tank. Thanks! P.S. I just joined this group last week and I have been asking so many questions! I just want to thank everyone for putting up with all of my emails and for being so helpful! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Eric Martina University of Illinois Electrical Engineering ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
