Well I have seen 2 differnt types of curling through my experience.

The first is PH flucuation. This is known as the "claw". To fix, start checking ph daily and keep it the same.

The second is overwatering. Its more of a droop than a curl. This means there either isnt enough DO, and/or water temps are too high.

Hope this helps :thumbsup:
