Do guppies hide when pregnant

The easiest way to tell if a guppy is pregnant is to look for a dark spot under her tail toward the backside of the stomach. This dark spot is called a gravid patch and as the babies grow, this guppy gravid spot will increase in size while also becoming darker. (source)

Many pregnant female guppies start to exhibit behavioral changes, too. Females tend to get pretty aggressive when they’re pregnant. While they can exhibit some feisty behavior towards any fish that gets in her way, pregnant females tend to direct most of their anger at the males. Jun 11, 2021 (source)

It is not normal for guppies to lay on the bottom of the tank. In my experience, there are a number of reasons guppies lay on the bottom of the tank and these include illness, stress, and poor water quality. Pregnant females may also lay on the bottom of the tank prior to giving birth. (source)
The swimming up and down the glass in a pregnant guppy is a typical sign of giving birth thumbs2: When a female gives birth she releases a hormone which supresses the eating of the babies for 6 hours… so once they are born you have 6 hours the time to get them safe or add some moss etc. where they can hide in.
