Finding Nympho.

One of our goldfish hasn't been looking too well since Friday. It constantly looks like it's about to go belly up but every couple of minutes it starts swimming normally again. Then we found out that it was just the current from the filter swishing it around. It's been quarantined into a separate bowl now, but I don't think he'll survive overnight. His fins are barely moving, and his breathing has almost come to a stop. :(
