Ok before I start, yes I have learned my lesson. I found a porcupine puffer that I fell in love with at my lfs and it was housed in a community tank with fish and huge CUC and was strictly fed frozen brine shrimp. Well I brought him home and he ate all my fish except for my clown and killed my entire CUC. Is there anything at all I can do ? (Tank is by a window and has to have a CUC or there is algae blooms almost everyday my CUC did a great job at keeping it spotless) I have a huge copepod population but they are not cutting it. This is all in a fluval evo (yes I know it’s too small of a tank, but he’s still pretty small I will move him when he gains some size) my question is, Am I just screwed with a CUC or is there something that he will leave alone in the invertebrate world that he would leave alone ? I need my sand sifted and my algae eaten
