Sick Fish... Brackish Water

Over a year ago I inherited about 18 Pupfish (Cyprinodon variegatus) but I have been losing them to tumor like growths. I am now down to four. I just had to put this little guy away. The growth on his back is growing and he now has one on his mouth.

When I got them the water they lived in was disgusting. Originally I kept them as marine fish until I found out what they were and then moved them to a brackish environment. Anybody see anything similar on any fish? Matt?

As an aside, there are both bristleworms and gammarus shrimp surviving in 1.014 environment.
