Vienna_11.10.20_04:42 pm joe blow seems to be a surface dweller. But remaining in one place motionless, as seen in the video below, is highly unusual even for joe blow.
Vienna_11.10.20_ 04:38 pm The fish seem to have their own typical movement patterns. These patterns can also depend on the time of day (see movement patterns of forc and 1point below). As you can see in the picture above, there is a separate but accessible compartment in the aquarium. Only two fish entered the separated … Continue reading
I used a lamellophone, pressed it on the glass of the aquarium and played. The fish responded, but their response was equivocal. I felt that a demonstration that fish could learn to categorize stimuli as complex as music, according to a criterion as unnatural as musical genre, not only would show that they extract meaningful … Continue reading
I fed mosquito larvae from a sieve and learned that the fish easily get into the sieve. Next time I know how to catch them if I want to move them to another tank.
Vienna_14.07.20_12:47 pm There is algae growth again, but it’s a different species. I can’t identify it. They adhere to the plants, particularly to the Java fern and the glass surfaces. Unlike the cyanobacteria, you cannot wipe them off the surface. They stick firmly on it, especially on the plant tissue.
2point was no longer able to capture any of the brine shrimp. I think he sort of said goodbye – an astronaut floating in space.
Vienna 24.06.20_04:00 pm When I got home last night, 2point was floating on the surface. I was sure that he was dead; but he wasn’t. He shot away as I approached him. This afternoon [see picture above] I was again sure that he was dead. I couldn’t see an eye movement nor any other … Continue reading

6. Juni 2020, 11:07 am [mdm and 2point] mdm has an ulcer or sore. I think her health condition is not the best. Her scales seem rough and she also didn’t get rid of a thread of faeces for one day. One the first glance I thought 2point is dead. But he is tough. [I … Continue reading
2. Juni 2020, 01:06 pm [john dow] In the labs fish are fed with different food. Sometimes it is commercial fish food, sometimes they bred food for the fish. I will investigate on that. I remember a funny detail. In one source it was told that the zebra fish in the fish facility in Tübingen … Continue reading
2point is not recovering. I fear that he will be the next fish at the cemetery. However, he still has an appetite. Yesterday I was in a pet shop and asked for advice. According to the owner, it is not the cyanobacteria that caused the poisoning. Just something like bad luck. He also did not … Continue reading
Vienna_20.05.20_04:40 pm The day before I started to transfer the fish into another tank. The bowl served as an interstation. It is filled with a mixture of water from the initial aquarium and the new one to minimize the shock of altered water conditions. If you look closely, you will see that one of the … Continue reading
