I decided to build a home for small crabs.
Vampire Crab Geosesarma Dennerle.
Crab red devil Geosesarma Hagen.
The aquaterrarium 50x50x50cm was bought and a hole was drilled in the rear window.
In fact, the rear and front windows are conceived by the manufacturer as side, but the doors with handles
and a thick black stripe around them would interfere with the view, so it was decided to deploy
Next, it was necessary to divide the water part into two compartments - one for the inhabitants, the second for
technical needs. We needed solid material with holes so that the residents could not
to get into the technical compartment, and the water is easily circulated. Nothing suitable is at hand
it was found, but plastic balls from a once-bought external filter were lying around at home,
which are useless for biological filtration - unless the cat is allowed to play.
The balls were planted on an aquasilicone along the proposed coastal boundary.
From the foam cut out the land, which will later be glued to the balls with the same
With the help of polyurethane foam, a tube was installed for the fog generator based on the water level.
It was assumed that the fog will move along the water surface - and it happened, but as it turned out
later, it was my first mistake, which will later be corrected and described and below.
The coastline was covered with silicone, on which coconut peat was pasted. Right away
I will make a reservation, if someone goes my way, that peat should be wet. But not so with
water flowed in him, but SLIGHTLY hydrated. I used an ordinary atomizer for this,
gave the peat a little stand and moistened. Why is it important? Dry peat has a lot of peat
dust. If you pour it dry, the dust will stick in the first place, and the peat itself is only partially.
And then went to work with foam.
Pruning by stationery knife.
Painting with acrylic paint.
The brook is covered with silicone and pebbles are glued to it.
Then the entire assembly foam was coated with silicone and coconut peat pressed.
In each recess for the plants, holes were drilled and tubes were inserted. It's for
to ensure that the water does not sour with peat in these grooves, but flows down the pipe to the technical
The tubes were passed around silicone. After solidification, the extra sticking pieces of the tubes
were cut off. Why tube, and not just holes? The goal is to completely avoid
water contact with mounting foam.
Test of fog run. Steam is supplied by the most common household humidifier with an ionizer,
which gives moisture up to 99% and charges the air with anions (negatively charged ions
oxygen; About anions on the Internet a lot of information, for example, here
The background is pasted and the side wall is painted with the same acrylic paint along the outline of the slide.
A simple mechanical filter was made. A small pump supplies water to it from
a small internal filter (300 l / h), and already from the filter water gives rise to a stream.
Ceramic rings for biological filtration were placed in the technical compartment.
heater and the above pump.
Planting began, work on the landscape (stones, snags ...) and, best of all, the launch
crabs and fish. An infrared ceramic lamp is installed on top (it does not give light, only
heat; connected via a cheap thermostat bought on Aliexpress) Backlight LED-
Next to the paludarium is a small speaker (also with Aliexpress) which is very quiet
loudly unobtrusively loses in a circle mp3 with the sound of a stream murmuring, croaking a frog
and trill cricket. It seems that the sound really comes from the inside.
Now, as promised, I will go through the mistakes.
The first mistake was to install a fog-tube just above the water level. Like me and
wrote above, the fog spread over the water and it was beautiful, but it was heavy and did not rise up.
The slide remained dry under the infrared lamp, and the crab needs moisture 80-99% and
temperature 24-28 ° C. I had to cut the pipe, drill a new hole in the glass above the slide
and move the pipe there. Now the fog goes down, the whole hill is wet, humidity on the sensor
99%, temperature 26 ° C.
If the first error was corrected, the second, unfortunately, is not. I did not have
black aquasilicone, only transparent. Working with black, it would be easier to notice if somewhere
Silicone is missing. Either it was necessary to silicone in the 2 layer. Anyway, but there are a couple
places where water seeps and flows into the technical department of the foam, which I struggle
tried to escape! And you can discuss for a long time whether it is harmful when in contact with water or not - in
The internet has a lot of conflicting information. The only thing that calms me down a bit is
that i used polyurethane foam. Somewhere on the internet I read information that she also
harmless in water as a foam. As far as this information is correct, I can not judge.
And finally, a video for fun and relaxation.
