Sure.
First off Mudskippers are Brackish water fish, found in mangrove swamps. They are very used to the tides coming in and out. For the long term care of this fish it is imperative that they have a large area where they can exit the water and move about on land. I went with a sort of stepped paludarium approach, with the final step being a gentle slope on to a simulated beach. There was reasonable water flow and I ended up going with an immersed fluval unit for ease of integration. The fish go in and out of the water fairly frequently. I would encourage you to try to grow some mangroves in on the land. The sand should be damp, so as to add comfort for the fish. Some species are active climbers, so make sure they can't leap out. They will dig holes in the sand and have a lot of interesting behaviour. I'm actually in the process of trying to find an elegant way to incorporate waves into a paludarium as I'd like to try mudskippers again soon. They are great fish, they eat the standard fair and are colourful and interesting. You may want to include some mollies with them, and if you're brave some smaller crabs. Once again, they are best maintained with salt in the water. Good luck these are really interesting fish!
