Adieu S.F. III and Hola S.F. IV!!

So...it has come to pass AGAIN!! S.F. III has been visited by the Grim Reaper (hope he had his affairs in order). Frankly, Shawn & I are starting to think that Santa Claus Daddy (S.C.D. to those in the know) is killing the S.F. fish and stealing their souls! I know, creepy, but it is a bit weird. S.C.D. was always a quite little fish, timid and meek, but here he is surviving whatever befell the other three fish. And with each death, S.C.D. becomes more "normal" aka swimming around the aquarium and not hiding in the kelp at the bottom, eating the food from the top and not waiting for others to eat first, etc. What else are we supposed to think??? And, isn't it always the quiet ones that go out in their trenchcoats??? We'll keep S.C.D. close to monitor his actions, but if you don't hear from us in a while - check the tank!!!!
