Ok i have two yo yo loaches, i was told by LFS and what i read online that they sometimes play dead...meaning they lay on their sides and owners think they are dead. Well i have one that is so good i have tried netting him three times. Today he got me good by laying on the leaf of my plants just like he is sunbathing, i went to get him and he started swimming like mad again and just like he was mocking me i pulled net out and he went back to same spot.
