Have you tested your water?
Yes
If I did not test my water...
  1. ...I recognize that I will likely be asked to do a test, and that water tests are critical for solving freshwater health problems.
Do you do water changes?
Yes
What percentage of water do you change?
61-70%
How frequently do you change your water?
Every two weeks
If I do not change my water...
  1. ...I recognize that I will likely be recommended to do a water change, and water changes are critical for preventing future freshwater health problems.
For water changes I put every two weeks, but I range from every week to once a month, kinda depends on how much I procrastinate.


My turquoise severum started showing a lump right by his dorsal fin. He has been being harassed by the leporinus, not sure if it is the result of injury or not. Any ideas what this is?
