Zebrafish Observation Diary 15

 Monday, March 28th, 2022

Weather: cloudy and rainy

Situation：

The water was changed at noon, almost completely, and the water quality is now significantly better than before.

The fish are in very good shape, probably because the air pump is on, and every now and then there are fish jumping in the current spouting from the pump, many of them swimming close to the surface. They, like the bowl of seeds lying across the water, are somehow involved in the construction of their life form, a construction that comes from the inside out, a harmonious ecological beauty and a primal power.

The two ”golden sharks“ （China algae eater）still like to stand upright, against the glass of the tank, bouncing upwards. But the water level is low and the tank is deep, so even if they jump high, it is unlikely that they will jump outside the fish tank.

 


One interesting discovery: the blue-striped zebrafish looked black from the surface.

The water surface was close enough to smell a foul odor, I don't know if it was the smell left by the decomposing bodies of the dead crabs or the roots of the dead plants. The rhizome of the bowl of lily seeds is already very long and has some short whiskers growing out of the seed roots, and some pea-corn shaped buds are growing out of the very front of the stem.

How to Set up A Paludarium Tank

Image
  Why there is only half water in the Paludarium tank? The answer is that the Paludarium can provide a perfect habitat for amphibians (such as crabs, frogs, and salamanders), while the water can be used for small marsh fish such as medaka and betta as their home. More importantly, many aquatic plants are semi-aquatic plants, with their roots in the water, but their leaves sticking out of the water. In this way, they can take advantage of abundant sunlight and carbon dioxide, while also obtaining a permanent source of water and nutrients. Paludarium can be made from any container that can hold water. Use  aquarium lights  to promote plant growth, use driftwood and rocks to create a land space, and combine aquatic plants and land plants to create an amazing miniature nature landscape. The clever use of built-in filters can create waterfalls, enhance the visual effects of paludarium , while providing additional humidity for land plants and ample space for the growth of wet-loving species

Zebrafish Observation Diary on Mar 31

Thursday, March 31th, 2022 Weather: Sunny Community tank's situation: One of the algae eater was hiding in the crevices of the water ficus leaves. I heard from my colleague that it kept using its mouth to nibble on the water ficus leaves and the volcanic rocks, and my colleague suspected that it might have grown algae. We are afraid that it is hungry, so feed them, but most of the food just sink into the water, divided up by the other zebrafish. Another divide up still likes to hide in the hygger hollow tree trunk , it seems to have a clear division of labor, each has its own domain. I stared at the golden shark hiding inside the water ficus for a while, its mouth did look like a suction cup. Several of the bowl of lily seeds were starting to darken their seed casings, not black to be exact, but dark coffee, rather like chocolate beans, and similar in shape to chocolate beans.   Probably because the water level is much lower than before, so the zebra fish are always swimming from t
