Scaless fish treatments

[t fishguy]

Hello there, I was wondering if general cure could be used in treating scaless fishes

The fish in question is called a Dolphin fish and not much is known of this species
My fish, recently has been demonstrating signs of flashing or scratching however it is ever so mild and in no way excessive 
She also has no visible signs of ick or anything else
And apart from that, she is still active and has a good appetite,  could this be flukes or subclinical parasitic infections ? Hence is liquid super ick cure more suitable ? 

If my fish is probably fine could I use general cure anyways just to be safe ? 
Thank you

From what I have read API general cure is fine to use with scaleless fish @t fishguy
