I have 3 yoyo loaches that I want to remove from my tank as they have developed a taste for the eyes of my other fish. It's a tall 250 litre tank. I have 1 big net, 1 small net, I need tips and tricks for catching them as so far I've been unsuccessful (read failed miserably!). Tonight when kids are in bed, I'm prepared to tear down the tank if needs be. I have lots of plants, rocks and driftwood which I tried removing earlier to make the job easier but put it all back as I couldn't catch them. I can only just reach the bottom due to the height of the tank (and that's by sticking my arm in right to the shoulder!). Please, any suggestions!?!
