Advertisement I just tried to make some new sling cages for my little Chromatopelma cyaneopubescens & my Avicularia versicolor! It took a little while for me to put it all together. Here is how I did it. I went to Michael's and bought the acrylic containers. Used a small ruler and pen to mark the air holes. Drilled the air holes. I guess some people like to use a solider iron for that, but for me the drill work fine. Just use a sharp drill bit and don't force it through. Let the drill do the work, to avoid the large cracks. I just drilled air holes on all four sides, around the sides of the lid, and three rows of holes on two sides on the lower part of the container. Hopefully it isn't too may for my Avicularia versicolor. I guess I will have to see how fast the water evaporates in it. I am not too worried about mold since I have thrown in springtails. I mixed a small batch of grout with water and formed my backing. Keep in mind that too much will make the side heavy. I let this dry for a week. I never had the extra time to work on it during my work week but it took about a week to dry. That was with the heater on since it is winter here. I painted my background with acrylic paint and let that dry for a week. This didn't take as long to dry, but I just wanted to make sure. By the way, since it is a small area, paint brushes don't work. I had to cut a Q-tips in half to reach inside to paint the backing. I bought some cork bark and broke it into small pieces. I hot glued it together to shape a small hide for my slings. I also hot glued the fake plants onto it with some moss. I added Zilla Jungle Mix, Fir & Sphagnum Peat Moss. I am not sure what is the best kind for the tarantulas, but hopefully this will work okay. It is my first attempt at putting a sling cage together. I would love to know what you think along with any information that might be helpful. Please share your trials and errors to help me and other people who might be thinking about putting a cage together. Thanks so much! Karen P.S I am new at posting photos. It looks like I added my limit of photos on this post. I will try to add the rest of the photos to another post.
