Aquarium Advice Addict
I have 2 serpae tetras, I thought they were bloodfins, that is what the lfs told me but a bit of searching on the net proved that wrong. Over the last couple of days one of the serpae's has been swimming with his tail slightly down. Otherwise he acts normal, he plays, swims, eats and has no spots of ich that are visible. He looks like he is swimming to the surface all the time. Nitrites are 0 so are ammonia, ph is at 7.5, temp is 77. I just feel this is not normal behaviour for him. Any ideas or advice would be appreciated.
