Can I plug a multi-outlet adapter into a GFCI outlet?

Question

I have a GFCI outlet in my kitchen where I would like to plug in more than two things. I was thinking I could just add a multi-outlet adapter to one of the outlets, or maybe a short 1->3 plug extension cord for my purposes. I’m assuming this is probably frowned upon, but would it be functional?

Specifically right now in the GFCI outlet we have a bottle warmer plugged in; I would like to add to it a small fish take filter, LED light, and a fish tank heater.

You can absolutely plug in an extension cord to the GFCI outlet, and as long as the GFCI outlet was wired correctly, the GFCI protection extends to all the devices plugged into it.

However, I would advise you to stay away from this kind of multi outlet adapter, since it might cover the GFCI buttons making it harder to test and reset:

I suggest a side outlet tap such as the following product. Unlike the previous answer that suggested a six outlet cover with the screw in the middle, the project I provide below would actually fit into a Decora-style receptacle (outlet) such as a GFCI. The GFCI protection would extend to the devices that are connected.

The distance between the 2 sockets of a GFCI outlet are different then for a plain outlet, so a multi-plug adaptor won't fit.

Legal in your house. Not a business. Is it safe? Not necessarily. That's considered temporary. Has nothing to do with common sense as someone put as an answer. You are changing the design of the electrical engineer's plan.  If he wanted six outlets there, he/she would have designed six there.
You decide to plug in two heaters, it's melting and GFC is a false security.
Extension cords in a business are not legal because it's temporary use only.  That means unplugged and wound up. Christmas tree lights are not an exception.
