Zebrafish Observation Diary 13

Thursday, March 24, 2022

Weather: cloudy and rainy

Situation:

A colleague asked me, "The leaves of the water ficus are a little dark, is it lacking in nutrients?" I got up and looked at the ficus in the fish tank, and there were indeed some black patches along the edges of the leaves, but only a little bit along the leaves, not too much, but still bright green overall.



The zebrafish were in good shape, they got along well with the two new golden sharks and seemed to have become family. The only crab that survived liked to cower in the corner of the tank by itself, and I had to touch it with the air pump to make sure it was still alive.

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
