Hello, this is probably way off topic and maybe even stupid. I have wondered about this for a while though and so I sound off and wait for the experts to enlighten me. I have a large freshwater fan shrimp, the kind with large fan appendages for filter feeding. He eats microorgansims only, no fish food or anything. I have seen him get excited about microworms but he could have been eating the yeast in the solution. The tank he is in used to have lots of hair algae and was a bit problematic. Now it is the cleanest most healthy tank I have. I haven't changed any maintenance habits, the only difference is Mr. shrimp. He does not eat algae and yet it all disappeared. Could he be eating the stuff it used to feed on? Could he be eating cellular algae? Could he eat ick parasites? He eats microscopic stuff that he filters with his fans. I mean he sticks his whole fan in his mouth and licks off the stuff on it. Could he really be a sort of mini natural UV sterilizer? I apologize if this is incredibly stupid, but please tell me what you think. Teresa. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
