I did a tank stirrup ní water change yesterday. Removed two damsels that were heavy nippers so I could switch my tank over to more docile ones. I had a heavy copod population in one corner of my tank, but now they have free reign. They are covering my glass and itís kinda awesome! Should I get a target copod predator? Or just let them roam and be snacks for tobi puffers (when I get them) and dragonet?
