reef vs. frogs
Frogs are definitely cheaper than salt water stuff(also frog calls are a lot prettier than triggers munching on coral or pistol shrimp). The part I like best about frogs is that most either are currently, or could someday be captive bred. Some of the saltwater stuff will reproduce, like your clowns,cardinalfish, seahorses, (to those who can get them to reproduce goodluck with the larval stage)etc. and a few more on farms but mostly they seem to come directly from the ocean. I like having a hobby that is self sustaining outside nature. And just to preempt any backlash I'll just go ahead and include that I am supportive of RESPONSIBLE wild caught introductions into the hobby. Sometimes captive husbandry gets a bad name (sometimes it deserves it) but many species' continued existence, plant and animal, has depended on captive reproduction.
