What pet should I get for my 20 gallon tank? … any ideas?

I have a 20 gallon tall hexagon tank and I’m thinking about getting a new pet. I’m considering something like an invert or a small communal lizard. I’m open to other suggestions too. Anyone got any cool ideas?

If you’re looking for communal lizards, mourning geckos could be a good fit! Just keep in mind that if you get more than one, they might have babies. It’s not a big deal since you have a 20 gallon tank, but be prepared for that.

For an invert, a pinktoe tarantula (c. versicolor) could be a great choice! I have one, and she’s really calm. She also makes these beautiful webs that look amazing in the tank. Plus, they start out blue when they’re babies and then turn pink and red as they get older, which is super cool.
