No
You do not have to start training fish with a goldfish. Any fish will do but most people start with goldfish because they are cheap. All fish will learn the tricks but other fish are usually easier to learn about the tricks because goldfish have very short memory's.
Giraffes really have a very short Memory Span ..so short that it would be difficult to say.
NO! I did a science project on it. Not sure how long their memory is, but it is LONGER THAN A DAY, EVEN!
Short term memory is where you store stuff that you won't need for a very long time. Long term is the opposite.
The three main levels of memory are sensory memory, short-term memory, and long-term memory. Sensory memory holds sensory information for a very brief period, short-term memory stores information for a short time without rehearsal, and long-term memory has a more permanent storage capacity for information.
Fishes have relatively simple brains and short memory spans, so they may not remember things for very long. The exact duration of memory can vary between species but is generally short-term. Fishes rely more on instinct and learned behaviors rather than long-term memory.
yes it eats suck fish if not feeding well and this is very true
True. The frequency of light is very fast as it is a wave oscillating at a high rate. This high frequency corresponds to a short wavelength, which is the distance between two consecutive peaks of the wave.
very short
That is true.
true
Yes,they don't live very long
