Making a sloped beach

I'm making a beach tank with play sand for mudskippers and I'm worried that the sand will flatten out over time. Is there a good way to make a slope that keeps its shape?

 

You could add an occasional pebble or so the the sand or you could make a barrier around it.

 

I did some kind of bank in my tank too, and recently build a paludarium. Better use bigger rocks to build steps, otherwise the sandbank will likely flatten down more and more.

 

I have a wave maker that keeps a perfect beach.
Mine is very strong so I have to move it sometimes, but it will build a bank of sand overnight.

I'll have some big rocks buried, but in the past I've still had to fix the slope every once in a while because my frog uncovered the rocks when it bounced around. Would a layer of 1/2" pea gravel under the sand help, or would it just get mixed into the sand eventually?

I would say it will mix eventually. Maybe putting a plastic or acrylic divider into the tank, like a lawn edge. It can be hidden with some pebbles or rock.

 

Several acrylic dividers with increasing height from front to back seems like some people do to step up the sand.

 

I also use wavemaker for my tank. This helps my fish feel like living in a natural habitat giving them delight and comfort.

Hydor Koralia nano is my favorite wave maker. Lots of water movement for such a small impeller. Easy to adjust position and use, I just wish it had some way to control the speed.

Where do I find a wave maker? And will it work in a 36 gallon tank? I'd like to have a natural (mostly) sand and some gravel) beach for my Thai red claws. They will burrow into the sand to molt.

 

I got my wave maker on Amazon.

 

Aight thanks!

I think I gona use gravel for the slope and put a filter bed filter unterneat it with an air stone and the balls that beneficial bacteria grow on,(like a Gatorade bottle laying on its side with an air stone & those bacteria ball things inside and holes poked in it) place it deep in the 10 inch deep substrate then I'll use one of those clay lizard water bowls for the land and put dry sand in it.

I'll also get Malaysian trumpet snails because they burrow deep and move the sand and pebbles around, might be ideal for a deep substrate build.

Then use fine sand for the deep water section and a mF40 for the filter. Anubis plants and Java ferns. Neon tetras to entertain the crabs.
