hey my tank set-up is quite simple, i dont have tide simulators. i have sand and crushed coral as a substrate, that goes up gently like a hill so they can access the water. i have a cansister filter which hits this rock and creates a cool water fall. i have some slate that goes to this rock so they can climb on to it. they water has two floating lilypad plants made for pods. they love the lilipads, i also have some fake plants some driftwood. its a really cool setup and that tide simulator sounds cool btw. my skippers are small and can only eat anything that fits in their mouth. so the fiddler is out of the question of being eat by maybe when they get bigger they could eat it.:dance2: hope this made sense
