I've had green Anoles that lived 7 years for me, way past their life span of 4 years. The advantage to these is they don't take up alot of room if your limited to space. They only eat live crickets, I hated to feed them these live crickets, but that's all they eat. I had 4 in a tank at once, a 55 gallon high tank filled with a couple of plantsfor them ti sit on and branches for them to climb on. You can place an indoor ourdoor green rug mat for the bottom which is easy to clean or replace. The tank must be cleaned out at least once a month so mold or resudue or bacteria don't build up in there.I poured boiled water over the branches every couple of months to get rid of mold or bacteria or mildew. Keeping the tank clean is very important for their health. I kept them in another small tank as I cleaned their 55 gal. tank. I also made them a cage for them to soak up sun outside during the warm spring and summer months. During the winter I placed 2 reptile lites on top of the screeened lid top. And gave them a basking bulb for them to keep warm. They must have a warm area of 80 degrees in one or two spots, this is good for their digestion.
Boy this is turning into a book, sorry lol.
Anyway I find that Anoles are pretty easy to take of. Oh, just a note, during mating season they may attack each other and have to be sepparated, gotta give them plenty of space, that's why I had them in a 55 gallon tank, but still they would fight occasionally and I had to seppaatee them, they would fight to a bloody mess.
They are probably peaceful to watch, running about in their tank. Until they get into a fight! Fighting is not an issue i had much with parrots although it can happen. When my mom had them it was usually the small parrots which would get into fights. Of course hers was a breeding set up which is much different than just pets as i had. I hated the breeding esp when the chicks hatched and within days were taken from their parents to be handfed. Not a good business.
