As you know I moved one of my yoyo loaches into the 5 gallon for snail clean up duty. Imagine my amazement when I noticed the thing has disappeared. I hadnt seen it since I put it in the tank so I used the fish net to try and see if it was hiding. I moved all the gravel in that tank to the point to where I can see the bottom and the loach is just gone. I have no idea where it is. The top has been on the whole time and just for the hell of it I looked on the floor and it isnt there. Do these things know disappearing magic tricks or something? I also lost the one in the 29 gallon but was able to find it under the big castle how it fit under there I have no idea. DO they always hide like this? Im just baffeled as to what happened to the one in the 5 gallon. Do you think when I do a water change I will find it?
