Mudskipper Tank Or Paludarium - Littlefish

Ok, so I might be getting somewhere with the mudskipper tank. Phew.
I have built a divider to hold the sand/rock/pebbles in place for the land section, and am waiting for the silicone to dry. It's looking a bit grey at the moment, but I'm sure it will look better with the wood, etc. in place.
Had to cheer myself up by blanching some courgette and putting it in the bristlenose tank. It took Harry/Harri around 30 minutes of whiffling around the tank, up to the feeding rock, away to the log pile (repeat many times), before latching on to the courgette for 15 minutes before taking a break. He/she is back on the courgette again, so I think it's safe to say that it's another vegetable that I can offer.
No sign of Bertie, apart from a brief flash of gold from within the woodpile, so not sure if he likes courgette yet. 

@marquismirage I usually enjoy setting up a tank, but last week I had concerns that this one may be pushing me to my limits, even before I started.
When I visited the independent LFS today I aired some of my concerns, including the requirement for polystyrene under the stones, and my ability to even put together a tank suitable for mudskippers, when one of the guys said "we have faith in you", so no pressure. 
I hope that by the time I go back on Friday (to collect the weekly delivery of live bloodworms for the dwarf puffers) I am in a better mood (less stressed) and have some positive news for them.
I saw some correx at a DIY store today, and thought it would be useful, though eventually went with slate tile thingies to build the divider between land and water. I hope to finish the land area tomorrow, add the brackish water, and get the filter & heater running, with the aim of collecting the mudskippers Thursday/Friday.
It is hard work, but quite a nice way to spend my week off work. 

Aquarium road trip!  I'll chip in for fuel and, er, chips.

@Littlefish Hehe, if we wanted the easy life we'd keep rocks as pets.  What kind of mudskippers are you getting?  I don't know anything about the species kept in aquariums.  I remember seeing a documentary once with mudskippers living in mangroves swamps and the males had their own little islands which were their territory and they competed for the best islands.

Apologies to all.
The takeaway was postponed and I had roast chicken for dinner.
The mudskippers were delivered to my local MA in error, and the delivery company told them to keep them. As they had not been ordered the staff didn't have the latin name for them, but with much gawping at the tank and waiting for them to flash their fins so we could check the colours, we are confident that they are Periophthalmus barbarus (atlantic mudskipper). This means that they are larger and more territorial than some others, but they are very cute. There are three of them, we think it's two males and a female, and although there hasn't been too much trouble in the store tank, I'm preprared for the submissive male having to be moved to another tank if the dominant males causes problems in the new tank.
As for pictures, I will take some today. I could take a pic now, but it would mainly be rocks, wood, and buckets of sand/pebbles laid out on towels on the floor in front of the tank, after I pulled everything apart again yesterday. 

Got the tank almost done.
Currently adjusting temperature/humidity/salinity, and will also be adding more sand to the slope on the right.
Don't think I'll put any plants in the water, but will need to get some more long pieces of wood.
Phew, time for a rest now.

I agree totally.  Looks like your hard work is paying off!

@Littlefish Very impressive! All this started because of the orphaned fish in the store, or was this part of a longer term plan? You mentioned having mangrove trees some time ago so is it a coincidence?
I'm not sure if it is the same species but I think I recall a Life on Earth#1 episode with skippers defending burrows in the mud when the tide was out, returning to the burrow when it was in?
This suggestion isn't initially going to make your life any easier but.... they live in tidal areas and the tank looks like the water volume is quite small. Would it help having a sump and pumping water up into the top tank on a timer. This would give you a lot more water volume and the mud flat area at low water could be much larger and flatter removing the territorial pressure?
btw poor chicken - roasted!

@ColinB I hope that they will be comfortable with the environment, fingers crossed.
@Andy the minion basically yes, this all started from a delivery mistake at MA. However, this does show perfectly why I have so many tanks - I start out with the intention of something completely normal, get distracted, and then I'm spending months researching how to house something I've only ever seen on tv. I did buy some mangrove seedlings, but have not had much luck with them. The root systems have frown, but the leaves have not, so they are still in a pot rather than in the tank. I went with air plants in the tank because they can do well in warm, humid environments, and can be regularly misted.
I've seen a tank that has been set up as you describe, and has a twice daily flooding of the mudflat. Technically awesome and completely beyond me. I'd also seen mudskippers kept in paludariums, and originally thought this would be easier and more attractive, even though it is not an accurate representation of their natural environment. I started setting up the tank with a focus on the plants and land section, and soon found that it wouldn't work because my tank wasn't tall enough to accommodate the land and plants properly. That was why I emptied the tank to start again, trying to build the land section lower before finding there wasn't enough room for the filter in the water, then giving up and just going for air plants and what can only be described as an environment which has the correct water/humidity and contains any items smooth enough not to damage the mudskippers undersides whilst still giving them things to climb on and hide under.
I agree that there is not much water, and this was intentional. They spend 90% of their time out of water. They are not strong swimmers and can drown if they can't walk/climb out of the water. Most tanks I've seen during researching them either had very low water levels, or lots of wood in the water for the fish to climb on. I will need to get more wood as I used most of what I had pre-soaked for the woodpile in the bristlenose tank recently.
I know I'll have to make some adjustments to the tank as I go along, but I'm hoping that I've got enough of the basics right. 

I apologise in advance for the amount of photos I am likely to post today.
Here's another one - 2 fish exploring, one at the top of the bag, the fourth still at the bottom of the bag.

Love your updates and pics, Donna, such unusual fish! Great to see and I look forward to seeing your progress
