White Bump/mark On Cherry Barb.

[bauhaus]

Hi, all! Just noticed a whiteish bump that may be a little furry on the side of my Cheery Barb. It is near its gill!

Any ideas?

Just to add. It looks like the kind of thing near this Bettas gill.

Size of tank in gallons or litres.
How many fish and which type.
Water stats in ammonia, nitrite, nitrate, and ph.

The bump does it look hard or soft like filled with fluid.
Does the bump look smooth.
Does the bump look like a cauliflower.
Any redness to the bump.

I would issolate and try a bacterial med.
