Alright so I have a 55gal with 1 male JD. He is over 2 years old and has never had a tankmate. He looks so lonely, I would love to get a female JD(filtration is eheim pro 2 canister + ac 110) but I only have a petsmart/petco so the female would be SMALL. What are the odds of him killing her right off the bat?!
Thanks!
