Re: [Killietalk] another WhatIsIt

The attachment is a 50X micrograph, dark field. There are 3 
individuals in the Micrograph.

these slugs were moving a bit so they are out of focus just a bit. 
There looks to be a "shell" near the front of the animal. The 
anterior end has a lyre tail there are definite mouth parts on the 
front end. It looks like a white Planaria without the diamond shaped 
head but not quite as long. It does "Swim" or move through the tank 
water but mainly stays on surfaces. Being poked or startled, the 
animal shrinks into a sphere. Given room to move, the animal 
stretches out 3 times its girth and moves easily.

I thought Hydra were a big problem raising fry in "Natural setups", 
this is a new one.

Change as much water as often as you can!
