Hi hanoidiscus,

Sorry to hear that you have fry troubles. I'm afraid that you may have stunted your fry. Its not a good idea to treat small fry with any medication. Its a better strategy to treat the pair before they spawn. If the pair is healthy, there is no need to treat the fry. The problem I think you have here is Levamisole can cause fish to stop eating for several days. Adults tolerate that fine, but small young Discus fry need to eat well and often. They don't have the reserves to deal with not eating all or well for several days.

Its possible that you might get some growth still but Its not likely to be as good as if they ate normally when smaller. I'm sorry.

If you could post pics we might get a better idea of how bad they are stunted.

Many medications can delay the normal growthrate. You may try to do a catch-up
by doubling waterchanges.
