I have a Erythrinus K. in a 40 breeder by his/her self I was wondering if there were any possible tank mates that might be ok with my wolf for life, I know I do not have the largest tank but I was hoping I could maybe get one more in there, I have a pictus cat that is close to the same size in my community could I possible put him with the would or would this be asking for too much trouble?
