I think I'm going to stop at 2 colonies. IMO, I want to say that the time, maintenance and care of ants can be deceptive because a lot of people go into it thinking "oh, it's a bunch of tiny ants, easy!" but some ant colonies, if kept right, can go into the thousands or tens of thousands.
My camponotus colony only has about a 100 workers and they're eating one (1-2 instar) dubia roach nymph every other day so it does make me worry what two colonies hitting a thousand each would eat and drink. And that's with just a thousand, what if there's more?
Just glad I'm raising them myself and not buying them at the local pet stores that are insanely overpriced.
And there is a smell to them that leaks out from their formicarium, not so bad now but again, my colonies are still on their first year. I'm pretty sensitive to smells and it kinda messes with my asthma that I developed from maintaining feeder roaches.
Add: And yeah, like mentioned by the others, it's also how much space they'll take up and the idea of going on a vacation for a month or more and finding someone to take care of them.
I kinda feel like the average person would have more than enough to do keeping just one ant species and raising them to their maximum potential, especially if it was a medium / large species. But people are bored with just one ant colony.
