New Fish World

  Friday, March 25th, 2022 Weather: cloudy and rainy Situation: I changed about one third of the fish tank water at noon today. Watching the water level drop drastically, I felt a sense of joy in my heart, as if I could really change the water to replace all those years in the old tank. I set up a pot of water and waited for the water to be changed on Monday. The zebrafish and crabs are in good shape, swimming around endlessly besides the airstone .

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.

At first, when they were put into the water basin, they were very lively and twisted around. I heard from a colleague that the other two golden sharks she kept at home almost jumped out of the tank at night, and they were very restless when they entered the water basin. Later, it took a lot of effort to get them out. After getting them out of the tank and putting them in the tank, probably because it was a completely new envir

Tuesday, March 22, 2022 Weather: Sunny Situation: Everything is in good shape for the zebrafish in the tank .  Only the only crab that was alive was missing.  I searched for some time before I found that the crab had climbed up the stem of the water ficus to  spit  bubbles and wouldn't come down for half a day. It must have been very active.  Looking at it hiding in the gap of the water banyan, I remembered the game of hide-and-seek when I was young.
