Does anyone have any tips to acclimate mollies and guppies to saltwater? I also have a question if I could acclimate other fish to saltwater. I was thinking bumblebee gobies and knight gobies. My tank is a 20gallon so nano fish only!

This has also been my experience. Some fish develop a "wobble" when swimming. They typically disappeared within a week.I did this and all acclimated great. Over a month or so in the tank, many died, but I still have two. Doing well. I think corals and powerheads attributed to death.
Euryhaline fish like guppies and mollies should acclimate just fine. There's enough responses in this thread that I feel no need to say anything about that .
As for acclimating bumblebee and knight gobies to saltwater....I'm iffy about this. I understand that at the very least they are brackish water fish, but I've always seen them as "freshwater fish that venture into brackish water estuaries" and such, rather than "fish that actively live in fresh and salt water". It doesn't help that bumblebee gobies are a complex of species that are hard to identify. Some bumblebee species are full freshwater (that still like hard water), while others are full brackish.
The same can also be said about fish like archerfish. Like, there are some full freshwater species yes. And there are also species that thrive in brackish mangrove swamps. And still more, there are fish that live near the seashore to be considered saltwater.
A better option for a 20 gallon tank might be Pseudomugil cyanodorsalis. They've recently gained some popularity in the hobby, and are a nano euryhaline fish that's NOT a livebearing fish.
Right, I've been seeing way too many posts like this. Please just do your research and think about the ethics of doing so before adding salt in willy nilly.I have a 10g QT tank that I'm able to use to slowly bring them to full seawater over the course of a week. I've always wanted to try bb gobies too but I'm unable to source them locally atm. Although not a fish, I'm planning to see if I can convert Malaysian trumpet snails to full strength seawater. I've heard stories of people finding them still alive months after they've converted their freshwater tanks to salt and they are also used frequently in brackish setups. Just placed an order from someone who sells them already brackish, I'll see how they'll do within a few weeks. If all goes well, I'll have what's essentially breedable dwarf cerith snails
