[Killietalk] help-Fundulus parvipinnis



Does anyone have experience with keeping California killifish in
captivity?  These estuarine fish are difficult to maintain in the lab
for longer than a few weeks.  They don't do well in flow-through sea
water tanks.  I've held a number of them in static tanks for 2 months
now, and several are coming down ith an unusual pathlogy, although I
can't identify it by external inspection only.  I have attached a
picture of a sick killi; the symptom is an indentation across the
back, in front of the dorsal surface.  Looks as if the muscle is
collapsing from the inside.  No sign of external lesions/ulcers/etc. 
Any information would be much appreciated.

thank you,
JS
