It has a lump on its back. I guess it looks kinda fuzzy or like the scales are raised. The fish won't hold still long enough for me to tell what it is or better describe it or take a decent pic of it. It still swims normal and is eating. This tank is still being cycled, so keep that in mind.

the raised scales make me think it could be dropsy, not sure about the hump on the back tho.

i am kinda lucky, i havent had many diseases so i am not too good at identifying any other than the normal ones.

hopefully someone else will offer a suggestion or two.

The hump is the only place on the fish where the scales are affected. The rest of the fish is ok.

raised scales points me to dropsy as well try and get a picture if you can as that would help us help you

I don't know what happened, but the fish looks darn near normal again. Swimming around with enthusiasm. Thanks everybody, but my fish took care of itself.

You better bottle that one! Funky's special elixir!

Did you count them?

Count who?

it was possibly just an abrasion that has sorted its self out but if it was me i would keep an eye on the fish just to make sure

Clunkster's probaly right about the abrasion. I've several fish that regularly give me a scare, until I get a close look at it, and realise it's just a scratch, or gouge! Although a Lump is unusual - at least to me.

I meant count the Zebra's. In case it didn't get better, you looked at the wrong fish... unlikely I know, sort of 'tongue in cheek'.

I only have 2 zebra danios.
