That’s basically the mindset I have. I made a mistake once at buying a neon dottyback and adding him into my tank. I had 2 sexy shrimp that I loved. They were both gone within 2 weeks of adding the dottyback. I still have the dottyback and will not get anymore sexy shrimp until he parishes. He’s lucky he’s a pretty fish, otherwise I would have hosted the worlds smallest fish fry.May just leave it. I would never want to risk anything in the tank that could kill anything else. Of course that’s a risk with Everything, but I’d like to not take large avoidable risks. Plus, keeping everything at a healthy and happy capacity, caring for things properly is important.
