Ok, so, right now my formicarium colony is at maximum capacity with 30 workers (most max level), 61 black ants (most max level) and 52 wood ants (most max level). I am at 150/150 and I've been thinking about it being an issue in the future. This is because I'm pretty sure you only get to have your formicarium max capacity increased every time you do a formicarium challenge, right? So when 3.1 and 3.2 come out along with level 3's own formicarium challenge, I might miss out on having a 4th type of ant in my formicarium colony because I am at max capacity, and I don't want to sell my ants to make room if the new ant type is worth it (if it even is a thing when that update comes out). If I do have to sell my ants, I fear that selling them won't give me back the amount of food i spent on upgrading them, which could suck, because then i would have to do extra missions in order to get the food i need back in order to get my formicarium colony back to a state i prefer. If i am wrong about the whole selling and max capacity of ants thing, please let me know and tell me if this is an issue. I really love this game and i absolutely wouldn't mind doing missions over again because of how much fun the game is, i mean, i already do missions extra times for more stuff. But i still would like to know if i have to just to know.
