female borelli with lump under dorsal fin

[joller]

hey guys, noticed this lump on my female borelli, never seen anything like this its kind of under the dorsal and from what i can tell its symetrical, the fish is still about 2cm big so its really hard to see let alone photograph, as she keeps her distance fro the front of the tank

heres the best i could do

if anyone has an suggestions as to what it might be i'd like to hear it
thanks, joel.

The photo is out of focus, so we really can't see much of usefulness. What is her behavior like; normal or odd?

 

[joller]

she's normal, i'll try and get another picture but the lump itself is so small i doubt i can get a good pic

 

[joller]

couldn't get any decent photos so i took a video, hopefully it helps

its still not very good but its alot better than the photo, probably the last 10 seconds gives the clearest picture

I notice something in the fish, but i cant say anything, sorry.

thanks anyway, it looks like a cist or growth of some sort, i've never seen anything like this so ill start with daily water changes hopefully it will go away
