belly sliders

[giorid]

Hi guys,
I think my batch of wigglers have turned out to be belly sliders , when they were smaller they seemed to stay on the bottom of the tank because they saw their reflection and I thought that as they got bigger and stronger they would eventually swim normally but now, 3 weeks later, they still stay on the bottom, is this condition irreversible, is there something I can do that will cure them or should I use them as feeder fish.

to the best of my understanding there just the weak fish in the batch and there is nothing you can do about it, might be best trying to pair the fish off with different partners see if that helps ive seen it in the past and im unaware unless some one is forth coming with some info about how or even if it can be remedyed or avoided

Cheers RTS
