I have two weather/dojo loaches in my tank and today one of them was missing. Luckly i found him in the filter (scared me half to death when he jumped out when i removed the carbon bag). Ever since he's been racing all over the tank and i'm terrified he's going to jump back into the filter again. My other loach is perfectly calm and peaceful and there is no signs of stress in my goldfish either. Is this just a normal behavior for a loach? I know they can act up during a storm but its not raining or going to rain for days. I've done everything i can to "loach proof" my tank so he doesn't jump out but I'm just worried about the filter. I love my little loach but his racing around is starting to worry me! he's usually so calm and lying around most of the day unless it's feeding time. What could be the problem? Please help!
