Honestly, I don't know. Mine was in a fish only tank.
Be on the lookout for declining signs of your fish's health. I had mine for what?...a month?....it was perfectly fine the entire time. Then, it stopped eating one week. By the end of the week, it was no where to be found. Another week later and I finally started moving rock and found half of it's body, between a 30lb rock and the back wall of the tank.
I didn't expect it to live, as they have a bad survival rating, but I sure wanted to make it work.
