Also known as Japanese rice fish, medaka are small, freshwater fish native to Japan. And they are invaluable for space research. … Because the fish reacted so quickly to their new living situation, the researchers were able to observe the effects of microgravity on their bodies almost in real time.
Has there ever been a fish in space?
It does not surprise me that the mummichog was the first fish in space. For the mummichog, space is only the next logical step for a fish that has tried to conquer land.
Could a fish survive in space?

What fish went to space?
The medaka fish, a freshwater fish native to southeast Asia, were sent into space to see how microgravity impacts marine life, particularly how their skeletal system changes in a weightless environment.
Does space affect fish growth?
In a natural environment, stress affects fish briefly and their hormones quickly reset. But a fish confined in a closed space will go on stressing until its owner takes notice. Among these fluctuating elements is growth hormone, which plays a big part in the regulation of major physiological processes.
Can a fish survive in milk?
Fish can swim in milk but fish will not survive for long period. Milk has other ions in it in much higher concentrations than water. The tonicity of the solution would not be conducive to fish life. Even though the milk is mostly water it doesn’t matter since it’s a delicate balance.

Could fish live on the moon?
After testing the eggs by replicating the launch of the Russian Soyuz spacecraft, the researchers were able to discover the eggs of two fish species– European sea bass (Dicentrarchus labrax) and meagre (Argyrosomus regius) –- could survive being brought to the Moon, according to the study published in Springer.
Can fish drown underwater?

Can spiders spin webs in space?
TORONTO — A team of scientists from Switzerland and the United States say that spiders are able to use light to orient themselves while weaving their webs in the absence of gravity in space.
What is the result of lack of space?
Venturing into the environment of space can have negative effects on the human body. Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton (spaceflight osteopenia).
Do koi fish grow to their tank size?
