Hey my 6 inch senegal is bullying my 8 inch ornate and was wondering what I can do to stop them. They are in a 75 gallon for now, and an upgrade isnt possible for at least 6 months. Hiding places arent the problem, as I have 4 caves. Water parameters are Ammonia .25 ppm Nitrates 0 ppm Nitrite 0ppm ph 6.6. Thanks in advance.
