hi
i have a problem with one of my rummy nosed tetras, 1 of them has what looks like a worm either attached or inside its dorsal fin, the worm ( if thats what it is ) is white and about 3 millimetres long, its hard to see if it really is a worm, as the fish move so fast!, ive tried to get a photo but unable to get one so far! what ever it is it is bothering the fish, he keeps flicking the fin...has anyone any idea what this could be? and also what treatments i could use, i dont want to use any meds, more into natural products, so far ive done a
water change, although the water was fine, added some aquarium salts and started to use garlic guard in the food
any advice would be most welcome, thanks in advance.
