Help with ant colony I’ve accidentally grown

So I have a pet false tomato from that I keep in a 10 gallon terrarium and I noticed one or two little black ants in the tank and I didn’t think much of it but I decided to investigate and I found a massive (relatively speaking) colony that was partially visible from the back of the tank. I of course relocated my poor frog into a new tank but I did not want to kill this thriving colony of I believe to be Monomorium minimum??

I’ve always wanted to get into ant keeping but I’ve never been able to find a queen in nuptial flight despite yearly attempts. I want to keep this colony but I’m not sure where to begin as I made this terrarium for my frog and not ants and I don’t think it’s ideal for them but they are already well established in there. I’ve moved the tank and put a two inch smear of petroleum jelly so they don’t get out but that’s as far as I’ve gone.

It’s been 2 days and they have seemingly grown considerably since I spotted them. Does anyone have any suggestions on what I might be able to do? Where should I go from here? I can include more details and pictures if needed.
