This is an obituary of my beloved fishes to whoever loved them at personal visit to my home and from photo shots in flickr archive. Now, I have ONLY THREE black tetras. They sheltered in a small water tank after an emergency rescue from where they lived long ago. Others passed away. :(
Recently, I recognized that several fishes went inviable in their motion to catch preys and feeds. Dripping several shots of antibacterial liquid was everything that I had done because it had worked well on the same symptom before. One morning after a couple of days, corpses were floating beneath water surface. I came up with the fact that I had forgotten to wash the tank and fill fresh water so long time.
It was absolutely my fault not to clean the tank while most of the deceased had lived longer than their known longevity of three years. On the other hand, there is no doubt that the survived also pass away within one year or so regardless of my sincere care. However, the only and very thing that I have to do is still to deliver utmost affection for them.
The half of fishes in the tank passed away since the start of keeping.
The other half of fishes survived in honor but tamed like Pavlov's dog.
Motion around the water surface attracts fishes even when there is no feed on it.
As shown in the video, in response to finger move, fishes intensively jump up to water surface to catch pseudo-prey. :)
Intense sunshine smashes ecosystem in water tank. Threes fishes passed away due to high temperature. Thermometer reads 31 Celsius. Six fans on the head of tank cool down water temperature by 4-5 degrees.
Water tank at home had two new joiners yesterday, a couple of white Corydoras(es??), from E-mart. They will stay there with elder inhabitants. White colored one is the variety of original from Brazil. However, they must be bred somewhere in Korea, because the per-fish price is only 1,000 won. Anyway, their presense started to provide the whole water tank with bright hue, whereas striped color mixture overwhelmed it before. Longevity I wish! So many baby fishes had passed away since the start of water tank keeping, while suvivors became doubled in size.
