I've used maracyn with my fish without trouble. Even the cories occassionally mess with it, and they're still alive.
But maracyn is an erythomyacine (sp? too lazy to look it up) derivative, and erytho is a bacterial-static drug, ie prevents bacteria from growing and dividing. It might be possible that ingestion of maracyn upset the natural gut flora of your fish, causing a possible septic death if an overdose occured. But I have never heard of it happening to fish before. In rabbits yes, their gut flora is extremly sensitive, but not in a fish.
Like Revfred said, if the rest of the fish are okay, then I'd just chalk this death up as possible maracyn overdoes, but more likely idiopathic. Are you sure it is the same ELB that bothered the maracyn that was dead?
