I’m not familiar with lizards but I did a bit of research to help you out because I see no one has replied to this thread and want to help! So you could have about two Emerald Swifts together in there or about two Anoles and one Emerald Swift. Because Anoles need a minimum of 10 gallons and Swifts need about 20. I believe so anyway lol. Don’t quote me on that but I think that’s about right. I really don’t know much about lizards so I hope the research I did was correct! And don’t keep Swift males together because they are aggressive and territorial towards each other, I’m guessing the same for Anoles. So quick rule of thumb: 10 gallons for each Anole, 20 gallons for each Emerald Swift, don’t keep males together
hope this helps!
