I’m looking at getting a Dragon Goby, but I need to know if he will be ok in our aquarium?

My parents recently started a fresh water aqaurium. I was hoping to get a Dragon Goby for it because they are rather laid back and only go after sick or injured fish. However, my parents did no real research into what they were getting and I don’t want to get something that will be killed. I spent the morning sexing and researching what I could and here’s what we have…
2 Male Blue Gouramis
1 Male and 1 female black mollies (God help me there)
1 Male and 1 female Rainbow sharks
2 Pictus catfish (which can only be sexed by venting)
and 1 Palcastamus.
Should I get the Dragon Goby or say forget it?

Unfortunately, dragon gobies are better off living in a brackish tank, but can adapt/adjust to fresh water or entirely marine.

Check out this link! They get fairly large 5+ inches, are predatory so your Mollies might disappear if they’re tiny hehe.
its realy up to you but dont try and overcrowed your cage they will not liek it and he may get aggressive
If you have a very large tank and a softer substrate, they don’t really like harsh gravel. he needs about 30 gallons for just himself.
It is good that you did your research but what I think your search failed to tell you is that dragon gobys are brackish water(where a river is reaching the ocean) fish meaning that they need low level salinity. and a very large tank. If the tank is atleast 75 gallons and you have a sandy substrate then you could bring the salinity to 1.008 and acclimate mollies to be brackish water…the rainbows. catfish and gouramis are strictly freshwater.
Forget it. Dragon gobies are actually brackish fish, which means that they need a small amount of marine salt. The freshwater fish will be unable to tolerate this at all. Dragon gobies also get quite large, 15 inches in capitivity. In the wild, or very well cared for in the aquarium, they get to be about 24 inches. That’s 2 feet long! Here’s a link to more info about Dragon gobies: http://www.aquaticcommunity.com/gobyfish/dragon.php.
Based on the set up you laid out, you should have at least a 75 gallon tank. If you are getting a Common Plecostomus, it should be 100 gallons or more. They also get huge (20+ inches). The sharks should have 75 gallons.
I believe everything is pretty much compatible as long as your tank is big enough. If it is only 55 gallons, ditch the catfish, pleco, and sharks, and you should be fine.
Forget it.
No your dragon goby cannot live in this tank. Dragons need a brackish water tank. Although your mollies can also be housed with them (for a short time since once the dragons get larger will eat live fish) the other fish cannot. Sorry
