I was at my mom's and she had a bunch of spider babies trying to live in a small glass of water. I took the 3 biggest she had and placed them in my fish tank. The seem to be doing pretty well and their roots are growing like crazy. They are skinny water roots but getting really long, they have been in there for about 6 weeks. I figured that I would post a pic and share. I know eventually They will outgrow their space but for now its cool.
