Agressive forum is definately the best spot for this post....
If you are thinking about eels, check out Reef Fishes, Vol. One by Scott Michael. Great section on morays and other types of SW eels...
I have two snowflake eels and they are so much fun to watch and they are easy to care for they like to hand fed but I feed them with a graber type thing. And they seem to be growing very fast I would say the biggest tank you can get is the best. I have a 125 gal and they are growing out of it. And they love to swim through rock work. I hope this helps alittle
