FIsh Rubbing on Plants and Driftwood
1.) I know what Ich looks like and I do not see a single fish with ich on him/her
So I have a few fish that seem to rub themselves on a few plants/driftwood/rocks. I am not sure what could be causing this, however i have lost some fish post Hurricane Sandy.
I remove the fish as soon as possible but sometimes i do not notice it for a day or two later. I do about 15 gallon water changes 1x - 2x a week on my 55 gallon tank.
I recently bought a Golden Face Blue Ram - and gorgeous fish but now developing a swollen eye that is slight cloudy and looks like a bubble over the eye.
The temp of the tank is around 83 degrees. I keep an air stone in the tank 24/7 with a powerhead 425 GPH, and Eheim 2215 and Eheim 2217 in the tank.
After hurricane Sandy, I cleaned out the filters and the tank.
Lost so far 2x GBR, 2x EBR - I really do not want to lose my newest too.
Some of my hardier fish (Emerald Cory/Juhili Cory/Honey Gourarmi) they have been fine in the tank since June.
I would like to get these fish to stop rubbing against the tank, last week I checked I had zero ammonia in the tank.
NO3/Nit - also very small (do not have an exact number did not check this week)
What could I do to help these fish?
I do not want to loose any more fish, and I am religious about water changes... I have carbon in the tank from treating fish that developed Fin Rot after Hurricane Sandy.... (melafix) and carbon has been in the tank since Nov 20th - as a side note.
Thoughts/Questions? comments? Please help!
PH goes from 6.1 - 7.0 during the course of the day. I try to keep it around 6.5, but I have noticed at night time the fish have been going toward the top of the tank, so I knocked down the CO2 in the tank. So for the past couple of days its been sitting around 6.9/7.0.
