The strainer on the filter fell off and the little Del was in the intake...so yup...torn in half. My Sen was doing back flips for a few days and I finally put him down the same day I found the Del Both Polys in one day
i lost all of my albino senegal to backflips or flips or loss of balance or something along those lines. The longest some lasted in that condition was couple weeks, but eventually they all died. And it all happened out of the blue, so every single case was a mystery to me.
