my fader female flowerhorn has been scratching a few times in a day since last week..today the scratching has increased and i can see weird newly developed brown spots on one side of her which she has been scratching...plz see the image attached..is it velvet? how should i treat it?
i have two of the following meds with me---
1) Fish Medicure Blue liquid (Treatment of fungus, white spot, tail and fin rot)
2) Sera Costapur treatment for Ich and other parasites ( Contains : malachite green oxalate 0.18g ; Formaldehyde solution 5.89g ; aqua purificata ad 100 ml )
Do i need to remove sponge filter while treatment? Medicine Bottle instructs to remove carbon filter..
