I've had fish tanks since i was a kid. Freshwater tanks with live plants are alot of fun and rewarding. Saltwater is a vastly more complex and varied type of hobby.

Saltwater, everything is alive and filtering the waters. From tiny Copepods and Amphipods to reef dwelling fishes. Some have shells, some have bones and some, like the cowfish, have a hard cartilage structure.

The vast variety of life in the oceans continues to fascinate me.
