I think I have Camallanus worms in my female betta. She is bloated, lethargic, and not eating. She has been in my 55 gallon since it started, so I fear I must treat the while tank. I ordered levamisole and hope to treat when it gets here, which is 2 weeks from now. Anyone have any advice as to how to handle. Attached is the best puc I could get so far. It looks like a little white thread. Althougb I think Camallanus are usually red from blood.
