I had a weather loach that seemed active and healthy until I added a couple silver dollars to the tank. In just a few days they tore up his top fin pretty bad. I took the two silver dollars out when i noticed. Since then my weather loach has been much less active, but it wasn't until today that he has shown signs of death. I thought I saw his last seconds today. He started to swim unbalanced and his barbels were not pointed outward as usual... instead they were motionless, just flowing with the water. Then he started to lie still on the top of the water. Thinking he was dead, I took the net out.. but when I touched him he swam away and hid. He's now in some awkward position at the bottom of the tank. He's not eating and I'm pretty sure he's on his way out. Is their anything that can be done? and if not, is their any less painful way I can end his death prematurely?
