Ok. It's been a year now since i had my fire eels in a 65g tank(by the end of the month i will move them to my newly built 400g tank in my apt) The bigger one(around 16'' is thriving in my tank and he eats well e.t.s and has grown a lot since i bought him. As for my second one, it's a bit smaller(around 14'' and thinner) has stop eating earthworms or shrimps from my hand . It's been 3 weeks since he was eating from my hands and generally since then he's been acting very strange and i hereby fear the worst. He hasn't eaten anything for 3 weeks now and has started to get thinner, the food goes in front of him and he's scared and won't even smell it and last but not least he's started doing some speed laps around the tank and sometimes he even crashes on the tanks walls or the driftwood e.t.c. No visible fangus or fin rot or anything. On the outside he seems quite healthy. What can i do to save my little buddy? Any suggestions on what he may be having fellas?Please help me...
