Advertisement So I have a 10 G tank that will be free in the next month or two and id like to start a project that is a little different. So far Im thinking of one of the following: 1. H. incei communal set up with 6 H. incei size less then 1" 2. H. gigas communal set up with a pool 4 H. gihas at about 1" or so 3. I was thinking about getting a C. crawsahayi and setting up the tank for extensive tunneling using piping cut in half to help start her off. So which would you find most interesting? What other projects might be fun? Im not interested in debating weather or not a particular species is communal so if you just say try this (insert species) in a communal set up thats what im looking for.
