A horrible, horrible end to my day - Nemo was gone...

I agree with Chin and Dan, Beverly and others
Healthy fish will not get sucked in.

Your fish are dying. Do not add anything else until you determine why this is happening.

I don't think my fish are all dying - This is the only fish that I've had issue with, and this was also the smallest 'fish' in the tank. I've noticed no signs of any illness with any other fish in my tank, and as was stated, and mentioned with Scavenger above, the intake was heavily broken and the impeller is within 1/8th" from the intake.

I'll keep an eye on my tank, and I'm not planning on adding any further fish - but I don't want to make a jump in assuming my fish are ill in my tank when it's an isolated incident.
